“…a ḥadīth that is ḥasan and ṣaḥīḥ.”

This additional wording is also reported by him, by Abū Dāwūd, and by Aḥmad in one of his narrations. He and Abū Dāwūd al-Ṭayālisī likewise transmitted it through the chain of Sharīk from Ashʿath, adding:

“Then he said: The Messenger of Allah ﷺ commanded us: ‘When you are in the mosque and the call to prayer is made, let none of you leave until he has performed the prayer.’ ”

Al-Munḏirī remarked, “Aḥmad narrated it, and its chain is sound,” while al-Haythamī said, “Its narrators are the narrators of the Ṣaḥīḥ.”

I reply: With this extra wording the report is not authentic, for it is uniquely related by Sharīk, and he is not strong in what he narrates on his own, as al-Darāquṭnī pointed out. In al-Taqrīb he is described as “truthful but prone to error.”

Furthermore, neither al-Bukhārī nor Muslim relied on him; Muslim only cited him for corroboration, as al-Dhahabī made clear in al-Mīzān. Hence al-Haythamī’s blanket statement that “its narrators are the narrators of the Ṣaḥīḥ” is inaccurate, for it gives the impression that all of them are relied upon in the Ṣaḥīḥ, which is not the case.

The ḥadīth is, however, also found—traced back to the Prophet—through another route from Abū Hurayrah, as will be mentioned later. Personally I have not yet located its chain in order to judge it, although the comments of al-Munḏirī and al-Haythamī outwardly suggest that it is strong, as you will see.
