The word(s) "blot" appears 15 time(s) in 15 verse(s) in Quran in Abdullah Yusuf Ali translation.

(11) Those who believe and work righteous deeds,- from them shall We blot out all evil (that may be) in them, and We shall reward them according to the best of their deeds.

(12) If He so pleased, He could blot you out and bring in a New Creation.

(13) If it had been our Will, We could surely have blotted out their eyes; then should they have run about groping for the Path, but how could they have seen?

(14) What! Do they say, "He has forged a falsehood against Allah"? But if Allah willed, He could seal up thy heart. And Allah blots out Vanity, and proves the Truth by His Words. For He knows well the secrets of all hearts.

(15) If any men among you divorce their wives by Zihar (calling them mothers), they cannot be their mothers: None can be their mothers except those who gave them birth. And in fact they use words (both) iniquitous and false: but truly Allah is one that blots out (sins), and forgives (again and again).
