حَدَّثَنَا ابْنُ السَّرْحِ وَمَخْلَدُ بْنُ خَالِدٍ قَالَا حَدَّثَنَا سُفْيَانُ عَنْ مُحَمَّدِ بْنِ الْمُنْکَدِرِ قَالَ حَدَّثَنِي مَنْ سَمِعَ أَبَا هُرَيْرَةَ يَقُولُ قَالَ أَبُو الْقَاسِمِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا کَانَ أَحَدُکُمْ فِي الشَّمْسِ وَقَالَ مَخْلَدٌ فِي الْفَيْئِ فَقَلَصَ عَنْهُ الظِّلُّ وَصَارَ بَعْضُهُ فِي الشَّمْسِ وَبَعْضُهُ فِي الظِّلِّ فَلْيَقُمْ
سنن ابودوٗد · Hadith 4821
Narrated Abu Hurairah: Abul Qasim ﷺ said: When one of you is in the sun (Shams)--Makhlad's version has "fay"--and the shadow withdraws from him so that he is partly in sun and partly in shade, he should get up.
