Sahih Muslim
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ إِدْرِيسَ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ أَسْمَاءَ، قَالَتْ قُلْتُ يَا رَسُولَ اللَّهِ إِنَّ أُمِّي قَدِمَتْ عَلَىَّ وَهْىَ رَاغِبَةٌ - أَوْ رَاهِبَةٌ - أَفَأَصِلُهَا قَالَ " نَعَمْ " .
Asma' daughter of Abu Bakr reported: I said: Messenger of Allah, my mother, who is inclined or scared has come to me. Should I (even An her position of being opposed to Islam) treat her well? He said: Yes.
