Ibn Ḥajar says in Fath al-Bārī: “The Messenger of Allah ﷺ pursued verification to the utmost degree, and this occurred only after the man had confessed four times—clearly confirming that the number is a condition.”
5 – The prescribed penalty for a previously married adulterer is to stone him with rocks until he dies, and no pit is to be dug for him beforehand.
6 – The presence of the ruler or his deputy is not a prerequisite for carrying out the ḥadd, though it is preferable that one of them attend to prevent injustice and any tampering with the limits set by Allah, Exalted is He.
7 – It is permissible to execute the ḥudūd in the funeral-prayer area; in the early days they designated a special place for the prayer over the dead.
8 – The ḥadd serves as expiation for the sin for which it is applied. This is a point of consensus and is stated explicitly in his ﷺ saying: “Whoever commits any of those acts and is punished for it in this world, that punishment is his expiation.”
9 – The sin incurred by acts of disobedience is erased by sincere repentance; this too is unanimously accepted among Muslims.
10 – The ruler or judge should initially turn away from a person who confesses to adultery, for he may have done something that does not actually entail the ḥadd while believing that it does; the ḥudūd are averted in the presence of doubts.
11 – This episode represents a lofty virtue of Maʿiz (may Allah be pleased with him): he came forward of his own accord, motivated by anger for the sake of Allah and a desire to purify himself, even though the Prophet ﷺ turned away from him and prompted him with words that could have absolved him of the penalty.
Difference of the scholars
The scholars have disagreed: is it a condition that the confession to adultery be made four times or not?
Imam Abū Ḥanīfah, Imam Aḥmad, and the majority of scholars—including al-Ḥakam ibn ʿUtaybah and Ibn Abī Laylā—hold that four confessions are indispensable. They base this on the present ḥadīth, for the Prophet ﷺ did not carry out the ḥadd on Maʿiz until he had borne witness against himself four times; they also draw an analogy with testimony to adultery, which is not accepted from fewer than four witnesses.
They do not stipulate that the confessions be made in separate sittings, unlike the Ḥanafīs.
