اللَّهُمَّ اجْعَلْ قَبْرِي رَوْضَةً مِنْ رِيَاضِ الْجَنَّةِ وَلَا تَجْعَلْهُ حُفْرَةً مِنْ حُفَرِ النَّارِ
Allahummaj'al qabri rawdatan min riyadil-Jannah wa la taj'alhu hufratan min hufarin-Nar
O Allah, make my grave a garden from the gardens of Paradise, and do not make it a pit from the pits of the Fire.
The Prophet ﷺ said: "The grave is either a garden from Paradise or a pit from the Fire." Two possible states for the same 6x2 foot space. The du'a is stark in its binary: garden or pit, no middle ground. What determines the outcome is your deeds and your faith. This du'a asks Allah to convert that dark, narrow space into an expansive, illuminated meadow of Paradise.
