Sunan Abi Dawud, Hadith 4743

The tradition mentioned above has also been transmitted by Umm Salamah through a different chain of narrators to the same effect. This version has : He who disapproves is guiltless, and he who disapproves is safe. Qatadah said : it means one who feels its disapproval in his heart, and one who expresses disapproval in his heart.

حَدَّثَنَا ابْنُ بَشَّارٍ، حَدَّثَنَا مُعَاذُ بْنُ هِشَامٍ، قَالَ حَدَّثَنِي أَبِي، عَنْ قَتَادَةَ، قَالَ حَدَّثَنَا الْحَسَنُ، عَنْ ضَبَّةَ بْنِ مِحْصَنٍ الْعَنَزِيِّ، عَنْ أُمِّ سَلَمَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم بِمَعْنَاهُ قَالَ ‏:‏ ‏ "‏ فَمَنْ كَرِهَ فَقَدْ بَرِئَ، وَمَنْ أَنْكَرَ فَقَدْ سَلِمَ ‏" ‏ ‏.‏ قَالَ قَتَادَةُ ‏:‏ يَعْنِي مَنْ أَنْكَرَ بِقَلْبِهِ، وَمَنْ كَرِهَ بِقَلْبِهِ ‏.‏
