Sunan an-Nasa'i, Book 21, Hadith 190 (In-Book) ⓘ

It was narrated that 'Ali said: "I said to the Prophet: 'Your paternal uncle, the old misguided man has died. Who will bury him?' He said: 'Go and bury your father, then do not do anything until you come to me.' So I buried him then I came, and he told me to perform Ghusl and he prayed for me, and he mentioned a supplication that I do not remember."'

أَخْبَرَنَا عُبَيْدُ اللَّهِ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا يَحْيَى، عَنْ سُفْيَانَ، قَالَ حَدَّثَنِي أَبُو إِسْحَاقَ، عَنْ نَاجِيَةَ بْنِ كَعْبٍ، عَنْ عَلِيٍّ، قَالَ قُلْتُ لِلنَّبِيِّ صلى الله عليه وسلم، إِنَّ عَمَّكَ الشَّيْخَ الضَّالَّ مَاتَ، فَمَنْ يُوَارِيهِ قَالَ ‏:‏ ‏ "‏ اذْهَبْ فَوَارِ أَبَاكَ وَلاَ تُحْدِثَنَّ حَدَثًا حَتَّى تَأْتِيَنِي ‏" ‏ ‏.‏ فَوَارَيْتُهُ ثُمَّ جِئْتُ فَأَمَرَنِي فَاغْتَسَلْتُ وَدَعَا لِي، وَذَكَرَ دُعَاءً لَمْ أَحْفَظْهُ ‏.‏
