Sahih al-Bukhari 6101
Narrated 'Aisha:
The Prophet did something and allowed his people to do it, but some people refrained from doing it. When the Prophet learned of that, he delivered a sermon, and after having sent Praises to Allah, he said, "What is wrong with such people as refrain from doing a thing that I do? By Allah, I know Allah better than they, and I am more afraid of Him than they."
حَدَّثَنَا عُمَرُ بْنُ حَفْصٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا الأَعْمَشُ، حَدَّثَنَا مُسْلِمٌ، عَنْ مَسْرُوقٍ، قَالَتْ عَائِشَةُ صَنَعَ النَّبِيُّ ﷺ شَيْئًا فَرَخَّصَ فِيهِ فَتَنَزَّهَ عَنْهُ قَوْمٌ فَبَلَغَ ذَلِكَ النَّبِيَّ ﷺ فَخَطَبَ فَحَمِدَ اللَّهَ ثُمَّ قَالَ " مَا بَالُ أَقْوَامٍ يَتَنَزَّهُونَ عَنِ الشَّىْءِ أَصْنَعُهُ، فَوَاللَّهِ إِنِّي لأَعْلَمُهُمْ بِاللَّهِ وَأَشَدُّهُمْ لَهُ خَشْيَةً ".
