DUA FOR CONTROL AND PURIFICATION OF NAFS
Recite the following dua for control and purification of nafs after Salat with full faith in Allah to ward off evil thoughts:
Allahumma ati nafsi taqwaha wa zakkiha Anta khairu man zakkaha wa Anta waliyyuha wa maulaha
O Lord! Bestow Taqwa on my Nafs and safeguard it from all kinds of evils.
Only You can purify it in
the best manner.
And You are Most-Forgiving, Most Merciful.
