Narrated Anas (RA): When Allah's Messenger ( صلی اللہ علیہ وسلم ) (while on a journey) proceeded before the sun had declined from the centre of the sky, he ( صلی اللہ علیہ وسلم ) delayed the Zuhr prayer till the time of the 'Asr prayer; he ( صلی اللہ علیہ وسلم ) would then alight and combine the two prayers. If the sun declined before he ( صلی اللہ علیہ وسلم ) moved off, he ( صلی اللہ علیہ وسلم ) would offer the Zuhr prayer and ride (i.e. travel). [Agreed upon] . In the narration of al-Hakim quoted in the al-Arba'in with a Sahih Isnad, "He ( صلی اللہ علیہ وسلم ) prayed Zuhr and 'Asr then rode (his beast, to continue his journey.)" Abu Nu'aim has in his Mustakhraj of Muslim, "While on a journey, if the sun declined he ( صلی اللہ علیہ وسلم ) used to pray Zuhr and 'Asr together and then continue his journey."
