حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا حَاتِمٌ، - وَهُوَ ابْنُ إِسْمَاعِيلَ - عَنْ يَزِيدَ بْنِ أَبِي عُبَيْدٍ، عَنْ سَلَمَةَ بْنِ الأَكْوَعِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يُصَلِّي الْمَغْرِبَ إِذَا غَرَبَتِ الشَّمْسُ وَتَوَارَتْ بِالْحِجَابِ .
Salama b. al-Akwa’ reported that the Messenger of Allah (ﷺ) used to pray the evening prayer when the sun had set and disappeared (behind the horizon).
