Sahih al-Bukhari 734

Hadith text

Narrated Abu Huraira:The Prophet (ﷺ) said, "The Imam is to be followed. Say the Takbir when he says it; bow if he bows; if he says 'Sami`a l-lahu liman hamidah', say, ' Rabbana wa laka l-hamd', prostrate if he prostrates and pray sitting altogether if he prays sitting

Abu Huraira (رضی اللہ عنہ) se riwayat hai ke Nabi ne farmaya: "Imam ki pairvi ki jaati hai. Jab woh Takbir kahe, tum bhi kaho; jab woh ruku kare, tum bhi karo; jab woh 'Sami' Allahu liman hamidah' kahe, tum 'Rabbana wa lakal-hamd' kaho; jab sajda kare, tum bhi karo; aur agar woh baithkar padhe, sab baithkar padho."
