Sunan Ibn Majah Book 6, Hadith 1530

حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنْ أَبِي إِسْحَاقَ الشَّيْبَانِيِّ، عَنِ الشَّعْبِيِّ، عَنِ ابْنِ عَبَّاسٍ، قَالَ مَاتَ رَجُلٌ وَكَانَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ يَعُودُهُ. فَدَفَنُوهُ بِاللَّيْلِ. فَلَمَّا أَصْبَحَ أَعْلَمُوهُ. فَقَالَ ‏ "‏ مَا مَنَعَكُمْ أَنْ تُعْلِمُونِي ‏"‏ ‏.‏ قَالُوا كَانَ اللَّيْلُ وَكَانَتِ الظُّلْمَةُ فَكَرِهْنَا أَنْ نَشُقَّ عَلَيْكَ ‏.‏ فَأَتَى قَبْرَهُ، فَصَلَّى عَلَيْهِ ‏.‏

It was narrated that Ibn ‘Abbas said:“A man died whom the Messenger of Allah (ﷺ) used to visit, and they buried him at night. When morning came, they told him. He said: ‘What kept you from telling me?’ They said: ‘It was night and it was dark, and we did not like to cause you any inconvenience.’ Then he went to the grave and offered the funeral prayer for him.”
