بِسْمِ اللهِ الرَّحْمٰنِ الرَّحِيْمِ
Die before you die (Mutu qabla an tamutu موتوا قبل أن تموتوا)
Mulla ‘Ali Qari (Rahimahullah) has mentioned it to be from amongst the proverbs and sayings of the Sufis.
One should ponder over death frequently, and even spend some time meditating on what would happen if one were to die and on the events that would follow in the Akhirah.
