Sunan Abi Dawud, Book 14, Hadith 2522 (USC-MSA) ⓘ
Narrated Abdullah ibn Amr ibn al-'As: A man came to the Messenger of Allah and said: I came to you to take the oath of allegiance to you on emigration, and I left my parents weeping. He (the Prophet) said: Return to them and make them laugh as you made them weep.
حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، أَخْبَرَنَا سُفْيَانُ، حَدَّثَنَا عَطَاءُ بْنُ السَّائِبِ، عَنْ أَبِيهِ، عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو، قَالَ : جَاءَ رَجُلٌ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فَقَالَ : جِئْتُ أُبَايِعُكَ عَلَى الْهِجْرَةِ وَتَرَكْتُ أَبَوَىَّ يَبْكِيَانِ . فَقَالَ : " ارْجِعْ عَلَيْهِمَا فَأَضْحِكْهُمَا كَمَا أَبْكَيْتَهُمَا " .
