It was narrated from Hittan bin ‘Abdullah that Al-Ash’ari said: “The Messenger of Allah صلی اللہ علیہ وآلہ وسلم addressed us and taught us our Sunnahs and our prayer. He said: ‘Make your rows straight, then let one of you lead the others. When he says the Takbir, then say the Takbir; when he says: “Walad Daleen” then say “Amin,” and Allah will answer you. When the Imam says the Takbir and bows, then say the Takbir and bow, for the Imam bows before you and stands up before you.’ The Prophet of Allah صلی اللہ علیہ وآلہ وسلم said: ‘This makes up for that. When he says: “Sami’Allahu liman Hamidah (Allah hears the one who praises Him),” say: “Rabbanawa lakal-hamd (Our Lord, to You be praise),” Allah will hear you, for indeed Allah, the Mighty and Sublime, has said on the tongue of His Prophet: “Allah hears the one who praises Him.” Then when the Imam says the Takbir and prostrates, say the Takbir and prostrate, for the Imam prostrates before you and rises before you.’ The Prophet of Allah صلی اللہ علیہ وآلہ وسلم said: ‘This makes up for that. Then when you are sitting, let the first thing that any one of you says be:(All compliments, good words and prayers are due to Allah. Peace be upon you, Prophet, and the mercy of Allah and His blessings. Peace be upon us and upon the righteous slaves of Allah. I bear witness that none has the right to be worshipped except Allah and I bear witness that Muhammad is His slave and Messenger).” (Sahih).
