Sahih al-Bukhari, Hadith 3183 ⓘ

Narrated Asma 'bint Abi Bakr: During the period of the peace treaty of Quraish with Allah's Messenger, my mother, accompanied by her father, came to visit me, and she was a pagan. I consulted Allah's Messenger, "O Allah's Messenger! My mother has come to me and she desires to receive a reward from me, shall I keep good relation with her?" He said, "Yes, keep good relation with her."

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا حَاتِمٌ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ أَسْمَاءَ ابْنَةِ أَبِي بَكْرٍ ـ رضى الله عنهما ـ قَالَتْ قَدِمَتْ عَلَىَّ أُمِّي وَهْىَ مُشْرِكَةٌ فِي عَهْدِ قُرَيْشٍ، إِذْ عَاهَدُوا رَسُولَ اللَّهِ صلى الله عليه وسلم وَمُدَّتِهِمْ، مَعَ أَبِيهَا، فَاسْتَفْتَتْ رَسُولَ اللَّهِ صلى الله عليه وسلم فَقَالَتْ يَا رَسُولَ اللَّهِ، إِنَّ أُمِّي قَدِمَتْ عَلَىَّ، وَهْىَ رَاغِبَةٌ، أَفَأَصِلُهَا قَالَ ‏ "‏ نَعَمْ، صِلِيهَا ‏" ‏‏.‏
