عَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ: ((إِذَا وَضَعْتُمْ مَوْتَاكُمْ فِي الْقَبْرِ، فَقُولُوا: بِاسْمِ اللَّهِ وَعَلَى مِلَّةِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ))
It is narrated from Sayyiduna Abdullah bin Umar that the Noble Prophet (peace and blessings be upon him) said: When you lower your deceased into the grave, recite this supplication: بِاسْمِ اللّٰہِ وَعَلٰی مِلَّۃِ رَسُوْلِ اللّٰہِ (In the name of Allah and upon the way of the Messenger of Allah).
