Abu ‘Amr — meaning, Al Awza’i — said that he asked Az uhri about the prayer of the Messenger of Allah صلی اللہ علیہ وآلہ وسلم in Makkah before the Hijrah to Al-Madinah. He said: “Urwah told me that ‘Aishah said: ‘Allah enjoined the salah upon the Messenger of Allah صلی اللہ علیہ وآلہ وسلم, and the first thing that He enjoined was two Rak’ahs at a time, then it was made complete four Rak’ahs while in the state of residence resident but the prayer when traveling remained two Rak’ahs, as it was first enjoined.” (Sahih)
