Hadith 20, 40 Hadith an-Nawawi
On the authority of Abu Masood Uqbah bin ’Amr al-Ansaree al-Badree (may Allah be pleased with him) who said:
The Messenger of Allah (peace and blessings of Allah be upon him) said, “Verily, from what was learnt by the people from the speech of the earliest prophecy is: If you feel no shame, then do as you wish.” [Al-Bukhari]
عَنْ أَبِي مَسْعُودٍ عُقْبَةَ بْنِ عَمْرٍو الْأَنْصَارِيِّ الْبَدْرِيِّ رَضِيَ اللهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صلى الله عليه و سلم "إنَّ مِمَّا أَدْرَكَ النَّاسُ مِنْ كَلَامِ النُّبُوَّةِ الْأُولَى: إذَا لَمْ تَسْتَحِ فَاصْنَعْ مَا شِئْت" .
