It was narrated from Umm Salamah from the Prophet ﷺ regarding:
“And that they will not disobey you in Ma’ruf (all that is good in Islam);” he said: “(It is about) wailing.”

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا وَكِيعٌ، عَنْ يَزِيدَ بْنِ عَبْدِ اللَّهِ، مَوْلَى الصَّهْبَاءِ عَنْ شَهْرِ بْنِ حَوْشَبٍ، عَنْ أُمِّ سَلَمَةَ، عَنِ النَّبِيِّ ﷺ {وَلاَ يَعْصِينَكَ فِي مَعْرُوفٍ} قَالَ " النَّوْحُ " .
