Sunan an-Nasa'i, Hadith 4163 ⓘ
It was narrated from 'Abdullah bin 'Amr that a man came to the Prophet and said: "I have come pledging to emigrate (Hijrah), and I have left my parents weeping." He said: "Go back to them, and make them smile as you made them weep."
أَخْبَرَنَا يَحْيَى بْنُ حَبِيبِ بْنِ عَرَبِيٍّ، قَالَ حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ عَطَاءِ بْنِ السَّائِبِ، عَنْ أَبِيهِ، عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو، أَنَّ رَجُلاً، أَتَى النَّبِيَّ صلى الله عليه وسلم فَقَالَ إِنِّي جِئْتُ أُبَايِعُكَ عَلَى الْهِجْرَةِ وَلَقَدْ تَرَكْتُ أَبَوَىَّ يَبْكِيَانِ . قَالَ " ارْجِعْ إِلَيْهِمَا فَأَضْحِكْهُمَا كَمَا أَبْكَيْتَهُمَا " .
