Chapter 15: Regarding sitting party in the sun and party in the shade - كتاب الأدب
حَدَّثَنَا ابْنُ السَّرْحِ، وَمَخْلَدُ بْنُ خَالِدٍ، قَالاَ حَدَّثَنَا سُفْيَانُ، عَنْ مُحَمَّدِ بْنِ الْمُنْكَدِرِ، قَالَ حَدَّثَنِي مَنْ، سَمِعَ أَبَا هُرَيْرَةَ، يَقُولُ قَالَ أَبُو الْقَاسِمِ صلى الله عليه وسلم " إِذَا كَانَ أَحَدُكُمْ فِي الشَّمْسِ " . وَقَالَ مَخْلَدٌ " فِي الْفَىْءِ " . " فَقَلَصَ عَنْهُ الظِّلُّ وَصَارَ بَعْضُهُ فِي الشَّمْسِ وَبَعْضُهُ فِي الظِّلِّ فَلْيَقُمْ " .
Narrated AbuHurayrah:
AbulQasim (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.
