Hadith 12:61
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.
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 "
