Companion’s words (mawquf) Muwatta Malik 119
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، كَانَ يَعْرَقُ فِي الثَّوْبِ وَهُوَ جُنُبٌ ثُمَّ يُصَلِّي فِيهِ .
Yahya related to me from Malik from Nafi that Abdullah ibn Umar used to sweat in a garment while he was junub and then pray with it on.
Reported by Malik (No. 119) and Ad-Darimi (No. 1012).
