Sa‘d ibn Abi Waqqas and the Crossing of the Tigris

Sharh Usul I‘i'tiqad Ahl al-Sunnah wa al-Jama‘ah by Abu al-Qasim al-Lalika'i (d. 418 AH / 1027 CE), translated to English by Rasheed Barbee (2020, Authentic Statements Publishing), reports on extraordinary events associated with the Companions of the Prophet, radhiyallahu 'anhum.

When the Muslim army under the command of Sa'd ibn Abi Waqqas pursued the Persians to the banks of the Tigris River, they found themselves at a standstill. The retreating Persians had destroyed every bridge and sunk every vessel, leaving the swollen, foaming river as an impenetrable barrier.

Sa'd summoned Salman al-Farsi, a Persian by birth who understood the enemy's mind. Salman's counsel was not military strategy but spiritual: ensure the army is upright before Allah, and Allah will provide a way. He circled the camp through the night and found the soldiers praying and preparing — and he returned satisfied.

Sa'd gathered the army at the river's edge. He declared his intention to cross, asked them to invoke the name of Allah, and pronounced three takbirs. On that signal, horsemen and foot soldiers alike entered the rushing water — and walked across its surface as though it were solid ground. When horses tired, islands of earth appeared beneath them momentarily, allowing rest before the crossing continued.

When the Persian soldiers on the far bank witnessed this, they were seized with terror, declaring that no mortal men could do such a thing.

The Muslims entered the Persian capital, seized its treasures, and returned them intact to 'Umar ibn al-Khattab in Madinah — every pearl accounted for.

The story is found in the classical Muslim historical tradition, and it is most commonly associated with the campaign led by Sa'd ibn Abi Waqqas during the great Muslim confrontation with the Persian forces in the seventh century.

After the decisive Muslim victory at the Battle of al-Qadisiyyah against the Sasanian Empire, the road was opened towards the imperial capital, Ctesiphon, known in Arabic sources as al-Mada’in. The Persian forces, in retreat, are said to have destroyed the bridges over the River Tigris in order to delay the advancing Muslim army. The river was reportedly swollen, its current strong and intimidating, presenting what appeared to be a formidable natural barrier between the Muslims and their objective.

According to the narratives preserved by historians such as Ibn Jarir al-Tabari, Ibn al-Athir, and Ibn Kathir, Sa'd ibn Abi Waqqas did not regard the river as an insurmountable obstacle. It is related that he placed his trust in God and encouraged his troops to do likewise. Supplication was made, hearts were steadied with tawakkul, and then the order was given to advance. The soldiers, mounted upon their horses, entered the waters of the Tigris. The chroniclers describe a scene that borders on the miraculous: the river did not overwhelm them, and neither men nor mounts were swept away. Some reports suggest that the water rose only to the chests of the horses, while others describe it in language that gives the impression that they traversed the river as though walking upon firm ground.

The crossing was accomplished, and the Muslim forces reached the opposite bank without catastrophic loss, an event later portrayed as a sign of divine assistance granted to a community whose faith was firm and whose cause was, in their understanding, just. In this way, the episode entered the corpus of early Islamic historiography as both a military achievement and a spiritual sign.

It is important, however, to note that these accounts appear in works of history rather than in rigorously authenticated hadith collections. As such, they belong to the genre of early Islamic narrative history, where events are often transmitted through chains of reporters but not always subjected to the same critical scrutiny applied to legal or theological traditions. For many Sunni scholars, the episode is understood either as a karamah — an extraordinary favour granted by God to righteous believers — or as a dramatic yet natural crossing later framed in elevated religious language. In either case, the story has endured as a powerful illustration of courage, reliance upon God, and the unfolding of one of the most consequential campaigns in early Islamic history.

Within classical Sunni theology, reports of extraordinary events associated with the Companions were approached with a careful balance between affirmation and restraint. The starting point of Ahl al-Sunnah was the principle that karāmāt — extraordinary favours granted by God to His righteous servants — are real and possible. This affirmation was grounded in the Qur’anic narrative itself, such as the story of Maryam, who received provision miraculously, and the account of the man who brought the throne of Bilqis in an instant during the time of Prophet Sulayman, alayhissalam. These precedents established, in Sunni doctrine, that supernatural occurrences are not confined to prophets alone, though they differ fundamentally from prophetic miracles (mu‘jizāt).

Classical theologians such as Ahmad ibn Hanbal and Abu al-Hasan al-Ash'ari affirmed the reality of karāmāt as part of orthodox creed. Later creedal texts, including those attributed to Abu Ja'far al-Tahawi, explicitly state that the karāmāt of the awliyā’ (the righteous friends of God) are true. In this framework, the Companions of the Prophet ﷺ, being the most virtuous generation after the prophets, were certainly not excluded from the possibility of such divine favours.

However, Sunni scholars also maintained clear theological distinctions. A karāmah is not a proof of prophethood, nor does it establish new revelation or law. It does not elevate a Companion above the rank assigned to him by recognised sources, nor does it confer infallibility. The Companions, though honoured and upright, remained human beings who could err. Thus, even if a report of an extraordinary occurrence were accepted, it would not alter established doctrines concerning the finality of prophethood or the closure of revelation with the Prophet Muhammad ﷺ.

At the same time, scholars exercised caution regarding the transmission of such reports. The great hadith critics did not automatically authenticate every story that portrayed a Companion in miraculous terms. They distinguished between rigorously verified reports and those transmitted through weaker historical chains. While theologians affirmed the possibility of karāmāt as a matter of creed, historians and hadith scholars assessed individual narrations according to their isnād. Therefore, a story might be considered theologically possible yet historically unproven.

Furthermore, Sunni orthodoxy rejected exaggeration (ghuluw). Scholars such as Ibn Taymiyyah emphasised that genuine karāmāt occur to those firmly grounded in obedience to God and adherence to the Sunnah, and that extraordinary feats alone are not signs of sanctity. If an alleged miracle contradicted established revelation or sound reason, it would be dismissed. In this way, Sunni theology sought to prevent the elevation of saints — or even Companions — into quasi-prophetic figures.

In relation to reports such as the crossing of the Tigris, classical Sunni scholars would therefore adopt a layered approach. They would affirm, as a matter of creed, that God is fully capable of granting extraordinary assistance to His righteous servants. They would acknowledge that the Companions were among the most deserving of divine aid. Yet they would also scrutinise the historical chains of transmission and refrain from building doctrine upon reports that do not meet strong evidentiary standards.

Within classical Sunni ‘aqīdah, karāmāt are real but subordinate to prophetic miracles, possible but not doctrinally foundational, and subject to historical verification. This balanced position allowed Sunni scholars to preserve reverence for the Companions while safeguarding the theological boundaries of prophethood and revelation.

In the end, reports of extraordinary occurrences among the Companions — including the account of Sa'd ibn Abi Waqqas and the crossing of the Tigris — invite us to inhabit a space between reverence and rigour. Classical Sunni scholarship neither dismissed such narratives outright nor embraced them uncritically; rather, it affirmed the theological possibility of karāmāt whilst subjecting individual reports to historical scrutiny. In doing so, it preserved both the majesty of divine power and the integrity of prophetic finality. Whether one reads these accounts as literal manifestations of divine favour or as historically framed expressions of courage and trust, their enduring significance lies less in spectacle than in what they symbolise: steadfast faith, reliance upon God, and the moral seriousness of a generation that understood history itself to unfold under the sovereignty of the Divine. And Allah knows best.
