We were sitting in the mosque with Abu Hurairah when the muadhin gave the call to prayer. A man got up and walked out of the mosque. Abu Hurairah followed him with his gaze until he left the mosque, then said, "As for this man, he has disobeyed Abu Qasim."In another narration, he saw a man passing through the mosque on his way out after the adhan and said, "As for this one, he has disobeyed Abu Qasim ﷺ."
كنا قعودا في المسجد مع أبي هريرة، فأذن المؤذن، فقام رجل من المسجد يمشي، فأتبعه أبو هريرة بصره حتى خرج من المسجد فقال أبو هريرة: أما هذا فقد عصى أبا القاسم. وفي رواية: رأى رجلا يجتاز المسجد خارجا بعد الأذان، فقال: أما هذا فقد عصى أبا القاسم ﷺ.
Muslim narrated it in "The Masjids" (655) through Ibrahim bin Muhajir, from Abu Shatha, similarly, and Abu Dawud (536) added, through this route, that this took place during the Asr prayer.The second narration was also narrated by Muslim, but through Ashath bin Abu Shatha, from his father, and it contains a corroboration of Ibrahim bin Muhajir Bajali, who is disputed as a narrator.His statement, "then he has disobeyed Abu Qasim," carries the ruling of being attributed to the Prophet. Imam Ahmad narrated it (10933) through Masudi and Sharik, both of them from Ashath, in similar wording, and Sharik added at the end, "The Messenger of Allah ﷺ commanded us, if you are in the masjid and the call to prayer is made, none of you should leave until he has prayed." Sharik has weak memory, and Masudi, although his memory became confused later in life, was corroborated in Muslim's narration.Tabarani narrated it in "Al-Awsat" (3854) through another route, from Abu Musab, who said Abdul-Aziz bin Abu Hazim told us, my father and Safwan bin Salim told me, from Saeed bin Musayab, from Abu Hurairah, and its wording is, "No one hears the call in this masjid of mine and then leaves it except for a need, and then does not return to it except a hypocrite."Tabarani said, "Abu Musab narrated it alone, and no one narrated it connected from Abu Hurairah except Safwan and Abu Hazim." End of quote.I say, the fact that Abu Musab alone narrated it does no harm, for he is trustworthy. He is Ahmad bin Abu Bakr bin Harith bin Zurara bin Musab bin Abdul-Rahman bin Awf Zuhri Madani, who narrated "Muwatta" from Malik. Ibn Hazm said, "In his version of Muwatta there are more than a hundred additional hadiths," and Daraqutni ranked him above Yahya bin Bukayr in narrating Muwatta. End of quote.The major hadith compilers narrated from him, though Abu Khaythama criticized him for giving legal rulings based on personal reasoning.Safwan bin Salim and Abu Hazim, who is Salama bin Dinar, are both trustworthy, and Haythami also graded it sahih, saying, "Its narrators are the narrators of the Sahih," Majma al-Zawaid (2/5).As for his statement, "No one hears the call in this masjid of mine," it does not restrict the general meaning found in Muslim's hadith, rather it is general, applying to all masjids, and the Prophet's ﷺ masjid is included in it with primary priority given its importance and special status. So perhaps Abu Hurairah narrated the hadith in its general form, and when he saw someone leave the Prophet's ﷺ masjid after the adhan, he cited it as evidence, both because it falls within the general meaning and because of its special status.
