He therefore made it obligatory." Then the man who had asked the Prophet—peace be upon him—turned away and came to the man and said: "Seal, O so-and-so, with 'Amin,' and receive glad tidings." This is the wording of Mahmud (1).

Abu Dawud said: Al-Maqra'i is a tribe of Himyar.

172 - Chapter on Clapping in Prayer

939 - Qutaybah ibn Sa'id narrated to us, Sufyan narrated to us, from al-Zuhri, from Abu Salamah, from Abu Hurayrah, who said: The Messenger of Allah—peace be upon him—said: "Glorification (tasbih) is for men, and clapping is for women" (2).

--------------------------------------------
(1) Its chain of transmission is weak due to the unknown status of Subayh ibn Muhriz al-Himsi, for only al-Firyabi—who is Muhammad ibn Yusuf—alone narrated from him, and Ibn Hibban mentioned him in "Al-Thiqat."
It was also narrated by Ibn Abi 'Asim in "Al-Ahad wal-Mathani" (1443), al-Tabarani 22/ (756), Ibn Mandah in his book on "The Companions"—as found in "Al-Isabah" 7/156—and al-Mizzi in the biography of Subayh from "Tahdhib al-Kamal" 13/111, via the path of Muhammad ibn Yusuf al-Firyabi, with this chain.

(2) Its chain of transmission is authentic. Sufyan: he is Ibn 'Uyaynah, and Abu Salamah: he is Ibn 'Abd al-Rahman ibn 'Awf.
It was also narrated by al-Bukhari (1203), Muslim (422) (106), al-Nasa'i in "Al-Kubra" (1131), and Ibn Majah (1034) via the path of Sufyan ibn 'Uyaynah, with this chain.
It was also narrated by Muslim (422) (106) and al-Nasa'i (1132) via the path of Yunus ibn Yazid, from al-Zuhri, from Sa'id ibn al-Musayyab and Abu Salamah, from Abu Hurayrah.
It was also narrated by Muslim (422) (157), al-Tirmidhi (369), and al-Nasa'i (1133) and (1134) via multiple paths from Abu Hurayrah.
It is found in "Musnad Ahmad" (7285) and (7550), and "Sahih Ibn Hibban" (2262).

This hadith indicates that the Sunnah for one whom something occurs during his prayer—such as alerting the one seeking permission to enter, or drawing the imam's attention, and the like—is to glorify (say "Subhan Allah") if he is a man, and to clap if she is a woman, striking the inner side of her right hand upon the back of her left palm.
