Sunan Abi Dawud, Hadith 4593

‘Amir b. sa’id on his father’s authority reported the Messenger of Allah as saying: The Muslim who offends most against the Muslims is he who enquires about something which has not been forbidden to men, and it is declared forbidden because of his enquiry.

حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا سُفْيَانُ، عَنِ الزُّهْرِيِّ، عَنْ عَامِرِ بْنِ سَعْدٍ، عَنْ أَبِيهِ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ إِنَّ أَعْظَمَ الْمُسْلِمِينَ فِي الْمُسْلِمِينَ جُرْمًا مَنْ سَأَلَ عَنْ أَمْرٍ لَمْ يُحَرَّمْ فَحُرِّمَ عَلَى النَّاسِ مِنْ أَجْلِ مَسْأَلَتِهِ ‏" ‏ ‏.‏
