The reciter: And Qutaybah ibn Sa'id narrated to us, saying: Al-Mufaddal—meaning ibn Fadhalah—narrated to us from 'Aqil, from Ibn Shihab, from Anas ibn Malik, who said:
When Allah's Messenger (ﷺ) (while on a journey) proceeded before the sun had declined from the centre of the sky, he (ﷺ) delayed the Zuhr prayer till the time of the 'Asr prayer; he (ﷺ) would then alight and combine the two prayers. If the sun declined before he (ﷺ) moved off, he (ﷺ) would offer the Zuhr prayer and ride (i.e. travel).
كان رسول الله صلى الله عليه وسلّم إذا ارتحل قبل أن تزيغ الشمس أخّر الظهر إلى وقت العصر ثم نزل فجمع بينهما فإن زاغت الشمس قبل أن يرتحل صلى الظهر ثم ركب Bulugh al-Maram 2:350.
