Sahih al-Bukhari, Hadith 2620 ⓘ
Narrated Asma' bint Abu Bakr: My mother came to me during the lifetime of Allah's Messenger and she was a pagan. I said to Allah's Apostle (seeking his verdict), "My mother has come to me and she desires to receive a reward from me, shall I keep good relations with her?" The Prophet said, "Yes, keep good relation with her. "
حَدَّثَنَا عُبَيْدُ بْنُ إِسْمَاعِيلَ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ هِشَامٍ، عَنْ أَبِيهِ، عَنْ أَسْمَاءَ بِنْتِ أَبِي بَكْرٍ ـ رضى الله عنهما ـ قَالَتْ قَدِمَتْ عَلَىَّ أُمِّي وَهْىَ مُشْرِكَةٌ، فِي عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم، فَاسْتَفْتَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم قُلْتُ {إِنَّ أُمِّي قَدِمَتْ} وَهْىَ رَاغِبَةٌ، أَفَأَصِلُ أُمِّي قَالَ " نَعَمْ صِلِي أُمَّكِ " .
