حَدَّثَنَا قُتَيْبَةُ، وَابْنُ، مَوْهَبٍ - الْمَعْنَى - قَالاَ حَدَّثَنَا الْمُفَضَّلُ، عَنْ عُقَيْلٍ، عَنِ ابْنِ شِهَابٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا ارْتَحَلَ قَبْلَ أَنْ تَزِيغَ الشَّمْسُ أَخَّرَ الظُّهْرَ إِلَى وَقْتِ الْعَصْرِ ثُمَّ نَزَلَ فَجَمَعَ بَيْنَهُمَا فَإِنْ زَاغَتِ الشَّمْسُ قَبْلَ أَنْ يَرْتَحِلَ صَلَّى الظُّهْرَ ثُمَّ رَكِبَ صلى الله عليه وسلم . قَالَ أَبُو دَاوُدَ كَانَ مُفَضَّلٌ قَاضِيَ مِصْرَ وَكَانَ مُجَابَ الدَّعْوَةِ وَهُوَ ابْنُ فَضَالَةَ .
Narrated Anas b. Malik :When the Messenger of Allah (ﷺ) proceeded before the sun had declined, he delayed the noon prayer till the time of the afternoon prayer, he would then alight and combine the two prayers. If the sun declined before he moved off, he would offer the noon prayer and rode (the beast) - may peace be upon him. Abu Dawud said: The narrator Mufaddal was the judge of Egypt. His supplication was accepted by Allah; he was the son of Fudalah
