One day the Prophet (ﷺ) ascended Safa mountain and said, "Oh Sabah! " All the Quraish gathered round
him and said, "What is the matter?" He said, Look, if I told you that an enemy is going to attack you
in the morning or in the evening, would you not believe me?" They said, "Yes, we will believe you."
He said, "I am a warner to you in face of a terrible punishment." On that Abu Lahab said, "May you
perish ! Is it for this thing that you have gathered us?" So Allah revealed:
'Perish the hands of Abu Lahab!...' (111.1)
Sahih al-Bukhari Book 65, Hadith 323
When the Messenger of Allah (ﷺ) got up for prayer, he would say the takbir (Allah-o-Akbar) when standing, then say the takbir when bowing. then say:" Allah listened to him who praised him," when coming to the erect position after bowing, then say while standing:" To Thee, our Lord, be the praise", then recite the takbir when getting down for prostration, then say the takbir on raising his head, then say the takbir on prostrating himself, then say the takbir on raising his head. He would do that throughout the whole prayer till he would complete it, and he would say the takbir when he would get up at the end of two rak'as after adopting the sitting posture. Abu Huraira said: My prayer has the best resemblance amongst you with the prayer of the Messenger of Allah (ﷺ).
