O Allah, make my grave a garden from the gardens of Paradise and do not make it — The Hereafter
اللَّهُمَّ اجْعَلْ قَبْرِي رَوْضَةً مِنْ رِيَاضِ الْجَنَّةِ وَلَا تَجْعَلْهُ حُفْرَةً مِنْ حُفَرِ النَّارِ
Transliteration: Allaahummaj-'al qabree rawdatan min riyaadil-jannati wa laa taj'alhu hufratan min hufarainn-naar
Translation: O Allah, make my grave a garden from the gardens of Paradise and do not make it a pit from the pits of Hell.
