Sunan Ibn Majah, Volume 5, Book 37, Hadith 4183 (DarusSalam) ⓘ
It was narrated from ‘Uqbah bin ‘Amr, Abu Mas’ud, that the Messenger of Allah said: “Among the words that people learned from the earlier Prophets are: ‘If you feel no shame, then do as you wish.’”
حَدَّثَنَا عَمْرُو بْنُ رَافِعٍ، حَدَّثَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ رِبْعِيِّ بْنِ حِرَاشٍ، عَنْ عُقْبَةَ بْنِ عَمْرٍو أَبِي مَسْعُودٍ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " إِنَّ مِمَّا أَدْرَكَ النَّاسُ مِنْ كَلاَمِ النُّبُوَّةِ الأُولَى إِذَا لَمْ تَسْتَحِي فَاصْنَعْ مَا شِئْتَ " .
