The Prophet's Right to Ijtihad and the Binding Nature of Sunnah

The incident of the Badr prisoners and Q 8:67-68 opens an important discussion in Islamic usul al-fiqh: did the Prophet Muhammad sallallahu alayhi wa-sallam have the capacity for ijtihad, independent scholarly reasoning that could potentially arrive at a less-than-optimal judgment, or was everything he said and did direct revelation (wahy)?

The Minority Position: Everything Was Wahy

A minority position holds that the Prophet sallallahu alayhi wa-sallam never spoke except by wahy, citing Q 53:3-4: "Wa-ma yantiqu 'an al-hawa, in huwa illa wahyun yuha" (وَمَا يَنْطِقُ عَنِ الْهَوَىٰ ۝ إِنْ هُوَ إِلَّا وَحْيٌ يُوحَىٰ) (He does not speak from personal desire; it is not but a revelation revealed). Under this view, every word, action, and decision of the Prophet sallallahu alayhi wa-sallam was direct divine instruction.

The Majority Position: Prophetic Ijtihad Was Real and Correctable

The overwhelming majority of Islamic scholars across all four major legal schools hold that the Prophet sallallahu alayhi wa-sallam had the genuine capacity for ijtihad in matters not directly covered by explicit revelation. Allah would either correct his ijtihad through subsequent revelation, or let it stand, and if it stood uncorrected, it became binding Sunnah through divine approval (taqrir ilahi).

The verse "wa-ma yantiqu 'an al-hawa" is understood to mean that the Prophet sallallahu alayhi wa-sallam never spoke out of base personal desire (hawa). This is not the same as saying every word was active wahy, rather, it means his character was so purified that even his independent judgment operated within divine guidance. The Q 8:67-68 correction itself proves the ijtihad position: if the decision about the prisoners had been direct wahy, Allah would have simply sent the wahy to not take ransom before the decision was made. The fact that Allah corrected it afterward shows the Prophet sallallahu alayhi wa-sallam was exercising ijtihad.

Examples of Prophetic Ijtihad from the Sunnah

Dr. Yasir Qadhi enumerates several well-established examples where the Prophet sallallahu alayhi wa-sallam made an independent decision that was subsequently adjusted:

(1) Cross-pollination of date palms: The Prophet sallallahu alayhi wa-sallam suggested Madinan farmers might not need to artificially pollinate their date palms. Some stopped; the harvest failed. He then said: "Antum a'lamu bi-umuri dunyakum" (أَنْتُمْ أَعْلَمُ بِأُمُورِ دُنْيَاكُمْ), "You know the affairs of your worldly life better than I do." This is a clear example of a judgment in technical worldly matters that was not wahy.

(2) Visiting graves: The Prophet sallallahu alayhi wa-sallam initially prohibited visiting graves to prevent unhealthy attachment, then later allowed and encouraged it: "Kuntu nahaytukum 'an ziyarat al-qubur, fa-zuruha" (كُنْتُ نَهَيْتُكُمْ عَنْ زِيَارَةِ الْقُبُورِ فَزُورُوهَا), his ruling changed based on developing circumstances.

(3) Al-ghilah: The Prophet sallallahu alayhi wa-sallam was inclined to prohibit a specific practice related to breastfeeding and marital relations. He surveyed the practice of Persians and Romans, observed no apparent harm, and did not issue a prohibition, discretionary judgment rather than pure wahy.

(4) Praying over the hypocrites of Tabuk: The Prophet sallallahu alayhi wa-sallam prayed the funeral prayer over Abdullah ibn Ubayy, the leader of the hypocrites. Umar ibn al-Khattab tried physically to stop him. Allah revealed Q 9:43: "'Afa Allahu 'anka, lima adhinta lahum" (Allah has pardoned you, why did you give them permission?), a gentle but unmistakable divine correction.

(5) Hajj mode: The Prophet sallallahu alayhi wa-sallam performed Hajj in the Qiran mode (combining Umrah and Hajj). He later said: "Law istaqbaltu mina al-amri ma istadbartu, la-ma sadaqtu al-hady wa-la-ja'altu-ha 'umratan", "If I were to do it again, I would not bring the sacrificial animal and would have converted it to Tamattu'." The Prophet sallallahu alayhi wa-sallam expressing a preference for a different choice, though his Qiran was valid.

(6) Uhud moment: When the Prophet sallallahu alayhi wa-sallam expressed anguish about the archers who disobeyed and implied a question about how Allah could forgive them, Allah revealed Q 3:128: "Laysa laka mina al-amri shay'" (لَيْسَ لَكَ مِنَ الْأَمْرِ شَيْءٌ) (The matter is not in your hands at all), correcting any implication that the Prophet sallallahu alayhi wa-sallam had authority to pronounce on divine forgiveness.

(7) Idhkhar exception in Makkah: When declaring Makkah's sacred status prohibiting the cutting of its plants, al-Abbas ibn Abd al-Muttalib asked for an exception for idhkhar (a fragrant grass used by silversmiths and builders). The Prophet sallallahu alayhi wa-sallam said: "Illa al-idhkhar" (إِلَّا الْإِذْخِرَ), "Except for idhkhar", immediately granting the exception through practical judgment.

The Binding Nature of All Prophetic Sunnah

A critical clarification: the ijtihad position does NOT mean that any part of the Sunnah is optional or open to rejection. The principle is that every Prophetic decision, whether it originated from explicit wahy or from ijtihad, is fully binding on all Muslims. The reasoning: if Allah did not correct a decision, divine silence constitutes approval (taqrir). If Allah corrected a decision, the correction itself is the new binding ruling. Either way, the outcome is binding Sunnah.

This directly addresses a rhetorical move used by some contemporary progressives who argue: "We can discard certain ahadith because the Prophet was just reasoning independently and may have been wrong." The ijtihad framework does not support this conclusion. Every judgment the Prophet sallallahu alayhi wa-sallam made, whether from wahy or independent reasoning left uncorrected, is fully authoritative and binding for all Muslims until the Day of Judgment. The Q 8:67-68 incident is, if anything, evidence of how seriously Allah takes even minor suboptimal choices by the Prophet sallallahu alayhi wa-sallam, correcting them immediately, rather than evidence that Muslims today may discount the Sunnah.
