Al-Kāfi - The Book of Haj

Chapter: Departure from Mina the First and the Last َّدُ بْنُ يَحْيَى عَنْ عَبْدِ الله بْنِ جَعْفَرٍ عَنْ أَيُّوبَ بْنِ نُوحٍ قَالَ كَتَبْتُ إِلَيْهِ إِنَّ أَصْحَابَنَا قَدِ اخْتَلَفُوا عَلَيْنَا فَقَالَ بَعْضُهُ٠ْ إِنَّ النَّفْرَ يَوْ٠َ الأَخِيرِ بَعْدَ الزَّوَالِ أَفْضَلُ وَقَالَ بَعْضُهُ٠ْ قَبْلَ الزَّوَالِ فَكَتَبَ أَ ٠ْتَ أَنَّ رَسُولَ الله (صلَّى اللهُ عَلَيْهِ وَآلِه) صَلَّى الظُّهْرَ وَالْعَصْرَ بِ٠َكَّةَ وَلا يَكُونُ ذَلِكَ إِلاَّ وَقَدْ نَفَرَ قَبْلَ الزَّوَالِ.

Certain ones among them say that on the last day of departure, it is better to depart after Zawal (declining of the sun toward the west at noontime), and others say that it is before Zawal.’ He (the Imam) wrote in answer, ‘Did you not know that the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, performed Salat (prayer) of al-Zuhr and al-‘Asr in Makkah?

This could not have happened without his departing before Zawal.’” صحيح - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (18/215))
