Sahih Al Bukhari (680)

عن سهل بن سعد (رضي الله عنه) "أن أناسا من بني عمرو بن عوف كان بينهم شيء فخرج إليهم النبي (صلى الله عليه وسلم) في أناس من أصحابه يصلح بينهم فحضرت الصلاة ولم يأت النبي (صلى الله عليه وسلم) فجاء بلال فأذن بلال بالصلاة ولم يأت النبي (صلى الله عليه وسلم) فجاء إلى أبي بكر فقال إن النبي (صلى الله عليه وسلم) حبس وقد حضرت الصلاة فهل لك أن تؤم الناس فقال نعم إن شئت فأقام الصلاة فتقدم أبو بكر ثم جاء النبي (صلى الله عليه وسلم) يمشي في الصفوف حتى قام في الصف الأول فأخذ الناس بالتصفيح حتى أكثروا وكان أبو بكر لا يكاد يلتفت في الصلاة فالتفت فإذا هو بالنبي (صلى الله عليه وسلم) وراءه فأشار إليه بيده فأمره أن يصلي كما هو فرفع أبو بكر يده فحمد الله وأثنى عليه ثم رجع القهقرى وراءه حتى دخل في الصف وتقدم النبي (صلى الله عليه وسلم) فصلى بالناس فلما فرغ أقبل على الناس فقال يا أيها الناس إذا نابكم شيء في صلاتكم أخذتم بالتصفيح إنما التصفيح للنساء من نابه شيء في صلاته فليقل سبحان الله فإنه لا يسمعه أحد إلا التفت يا أبا بكر ما منعك حين أشرت إليك لم تصل بالناس فقال ما كان ينبغي لابن أبي قحافة أن يصلي بين يدي النبي (صلى الله عليه وسلم)"

Sahl ibn Sa‘d narrated: There was a dispute amongst the people of the tribe of Banu `Amr ibn 'Auf. The Prophet (peace be upon him) went to them along with some of his companions in order to make peace between them. The time for the prayer became due but the Prophet (peace be upon him) did not turn up; Bilal pronounced the Adhan (i.e. call) for the prayer but the Prophet (peace be upon him) did not turn up, so Bilal went to Abu Bakr and said: "The time for the prayer is due and the Prophet (peace be upon him) is detained, would you lead the people in the prayer?" Abu Bakr replied: "Yes, if you wish." So, Bilal pronounced the Iqamah of the prayer and Abu Bakr went ahead (to lead the prayer), but the Prophet (peace be upon him) came walking among the rows till he joined the first row. The people started clapping and they clapped too much, and Abu Bakr used not to look hither and thither in the prayer, but he turned round and saw the Prophet (peace be upon him) standing behind him. The Prophet (peace be upon him) beckoned him with his hand to keep on praying where he was. Abu Bakr raised his hand and praised Allah and then retreated till he came in the (first) row, and the Prophet (peace be upon him) went ahead and lead the people in the prayer. When the Prophet (peace be upon him) finished the prayer, he turned towards the people and said: "O people! When something happens to you during the prayer, you start clapping. Really clapping is (permissible) for women only. If something happens to one of you in his prayer, he should say: 'Subhan Allah', (Glorified be Allah), for whoever hears him (saying so) will direct his attention towards him. O Abu Bakr! What prevented you from leading the people in the prayer when I beckoned to you (to continue)?" Abu Bakr replied: "It did not befit the son of Abu Quhafah to lead the prayer in front of the Prophet (peace be upon him).
