Sunan an-Nasa'i, Hadith 5341 ⓘ
It was narrated that Abu Sa'eed Al-Khudri said: "The Messenger of Allah [SAW] forbade Ishtimal As-Samma' and wrapping oneself in a single garment (that did not cover the private parts)."
أَخْبَرَنَا الْحُسَيْنُ بْنُ حُرَيْثٍ، قَالَ أَنْبَأَنَا سُفْيَانُ، عَنِ الزُّهْرِيِّ، عَنْ عَطَاءِ بْنِ يَزِيدَ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، قَالَ نَهَى رَسُولُ اللَّهِ صلى الله عليه وسلم عَنِ اشْتِمَالِ الصَّمَّاءِ وَأَنْ يَحْتَبِيَ الرَّجُلُ فِي ثَوْبٍ وَاحِدٍ لَيْسَ عَلَى فَرْجِهِ مِنْهُ شَىْءٌ .
