(Qaaf) 50 : 32
هَٰذَا مَا تُوعَدُونَ لِكُلِّ أَوَّابٍ حَفِيظٍ
This is what you are promised, for everyone who turns to Allah keeping the Covenant.
‘Keeping the Covenant’ means praying the ‘Sayyidul Isthigfar-the Most Exalted prayer to seek Forgiveness’ to be done in every dawn and dusk as explained in verse 2: 27. See explanation 9: 112; 38: 24, 30; and 50: 8.
