Book 56, Hadith 12
حَدَّثَنَا آدَمُ، قَالَ: حَدَّثَنَا شُعْبَةُ، عَنْ مَنْصُورٍ قَالَ: سَمِعْتُ رِبْعِيَّ بْنَ حِرَاشٍ يُحَدِّثُ، عَنْ أَبِي مَسْعُودٍ قَالَ: قَالَ النَّبِيُّ صلى الله عليه وسلم: إِنَّ مِمَّا أَدْرَكَ النَّاسَ مِنْ كَلاَمِ النُّبُوَّةِ الأُولَى: إِذَا لَمْ تَسْتَحْيِ فَاصْنَعْ مَا شِئْتَ.

Adam related to us: Shu‘bah related to us, from Mansur, who said: I heard Rib‘i ibn Hirash relate from Abu Mas‘ud, who said: The Prophet, Allah bless him and grant him peace, said: ‘Among the words of the first prophethood that people still recognize is: “If you feel no shame, then do as you wish.”’
