(36) باب قَوْلِ الْمَأْمُومِ إِذَا عَطَسَ خَلْفَ الإِمَامِ
It was narrated from Abdul-Jabbar bin Wa'il that :
His father said: "I prayed behind the Messenger of Allah (ﷺ) and when he said the takbir, he raised his hands to the bottom of his ears. When he recited: Not (the way) of those who earned Your anger, nor of those who went astray), he said: 'Amin,' and I could hear him although I was behind him. The Messenger of Allah (ﷺ) heard a man saying: 'Al-hamdu lillahi, hamdan kathiran tayiban mubarakan fih, (Praise be to Allah, much good and blessed praise.)' When the Prophet (ﷺ) said the salam and finished his prayer, he said: 'Who spoke those words during the prayer?' The man said: 'I did, O Messenger of Allah, but I did not mean anything bad thereby.' The Prophet (ﷺ) said: "Twelve angels hastened (to take it) and nothing is stopping it going all the way to the Throne.'"
