Arabic (Original)
حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ عَنْ عَبْدِ الْحَمِيدِ بْنِ جَعْفَرٍ حَدَّثَنِي أَبِي عَنْ حَكِيمِ بْنِ أَفْلَحَ عَنْ أَبِي مَسْعُودٍ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ لِلْمُسْلِمِ عَلَى الْمُسْلِمِ أَرْبَعُ خِلَالٍ أَنْ يُجِيبَهُ إِذَا دَعَاهُ وَيُشَمِّتَهُ إِذَا عَطَسَ وَإِذَا مَرِضَ أَنْ يَعُودَهُ وَإِذَا مَاتَ أَنْ يَشْهَدَهُ.
English Translation
Yahya ibn Sa'id narrated to us, from Abd al-Hamid ibn Ja'far: my father narrated to me, from Hakim ibn Aflah, from Abu Mas'ud, from the Prophet (peace and blessings be upon him), who said: "A Muslim owes his fellow Muslim four things: to answer him if he invites him, to invoke mercy upon him if he sneezes and praises Allah, to visit him if he falls ill, and to attend his funeral if he dies."
