Narrated by:Abu Mas`ud
Narrated Abu Mas`ud:The Prophet (ﷺ) said, 'One of the sayings of the early Prophets which the people have got is: If you don't feel ashamed (from Haya': pious shyness from committing religeous indiscretions) do whatever you like." (See Hadith No 690, 691, Vol 4)
حَدَّثَنَا أَحْمَدُ بْنُ يُونُسَ، حَدَّثَنَا زُهَيْرٌ، حَدَّثَنَا مَنْصُورٌ، عَنْ رِبْعِيِّ بْنِ حِرَاشٍ، حَدَّثَنَا أَبُو مَسْعُودٍ، قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم " إِنَّ مِمَّا أَدْرَكَ النَّاسُ مِنْ كَلاَمِ النُّبُوَّةِ الأُولَى إِذَا لَمْ تَسْتَحِي فَاصْنَعْ مَا شِئْتَ ".
