NASAI-KUBRA 9663:
from Abū Saʿīd al-Khudrī —
Messenger of Allah ﷺ forbade Ishtimal-As-Samma' (wrapping one's body with a garment so that one cannot raise its end or take one's hand out of it). He also forbade Al-Ihtiba' (sitting on buttocks with knees close to ʿAbdomen and feet apart with the hands circling the knees) while wrapping oneself with a single garment, without having a part of it over the private parts. (Using translation from Bukhārī 367)
الكبرى للنسائي ٩٦٦٣:
عن ابو سعيد الخدري —
«نَهَى رَسُولُ اللهِ ﷺ عَنِ اشْتِمَالِ الصَّمَّاءِ وَأَنْ يَحْتَبِيَ الرَّجُلُ فِي ثَوْبٍ وَاحِدٍ لَيْسَ عَلَى فَرْجِهِ مِنْهُ شَيْءٌ»
