It was narrated that Abu Basrah Al-Ghifari said: “The Messenger of Allah صلی اللہ علیہ وآلہ وسلم led us in praying ‘Asr in Al-Mukhammas He said: ‘This prayer was enjoined upon those who came before you, but they neglected it. Whoever prays it regularly will have a two fold reward, and there is no prayer after it until the Shahid appears.” And the Shahid is “the star.” (Sahih)
