Sahih Muslim , Hadith 2317 ⓘ
'A'isha (Allah be pleased with her) reported that there came a few desert Arabs to Allah's Messenger and said: Do you kiss your children? He said: Yes. Thereupon they said: By Allah but we do not kiss our children. Thereupon Allah's Messenger said: Then what can I do if Allah has deprived you of mercy? Ibn Numair said: (We has deprived) your heart of mercy.
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَأَبُو كُرَيْبٍ قَالاَ حَدَّثَنَا أَبُو أُسَامَةَ، وَابْنُ، نُمَيْرٍ عَنْ هِشَامٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ قَدِمَ نَاسٌ مِنَ الأَعْرَابِ عَلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فَقَالُوا أَتُقَبِّلُونَ صِبْيَانَكُمْ فَقَالُوا نَعَمْ . فَقَالُوا لَكِنَّا وَاللَّهِ مَا نُقَبِّلُ . فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " وَأَمْلِكُ إِنْ كَانَ اللَّهُ نَزَعَ مِنْكُمُ الرَّحْمَةَ " . وَقَالَ ابْنُ نُمَيْرٍ " مِنْ قَلْبِكَ الرَّحْمَةَ " .
