اللَّهُمَّ اغْفِرْ لِفُلَانِ وَارْفَعْ دَرَجَتَهُ فِي الْمَهْدِيِّينَ وَاخْلُفْهُ فِي عَقِبِهِ فِي الْغَابِرِينَ وَاغْفِرْ لَنَا وَلَهُ يَا رَبَّ الْعَالَمِينَ وَأَفْسِحْ لَهُ فِي قَبْرِهِ وَنَوِّرْ لَهُ فِيهِ
"O Allah, forgive (name of the dead person). Make him among the guided ones, raise his status and be his deputy among the grieving. O Lord of the two worlds, forgive us and him and make his grave wide and full of light". Prophet Mohammad (SAW.)
