Hamzah bin ’Amro Al-Aslami (RAA) narrated, ‘I said to the Messenger of Allah ( صلی اللہ علیہ وسلم ) ‘O Messenger of Allah ( صلی اللہ علیہ وسلم )! I find within me the strength to fast while traveling. Would there be any blame upon me if I were to do so?’ The Messenger of Allah ( صلی اللہ علیہ وسلم ) said to him, "It is a concession from Allah. Whoever takes it has done well. Whoever likes to fast, there is no blame upon him."Related by Muslim. And it's basic meaning is in Al-Bukhari and Muslim from the narration of Aisha (with the wording) "that Hamza bin 'Amro asked".
