All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His Slave and Messenger.
Allaah The Almighty Says (what means): {Allaah Does not Charge a soul except [with that within] its capacity} [Quran 2: 286]
- (what means): {and Has not Placed upon you in the religion any difficulty.}[Quran 22: 78 ]
- (what means): {So fear Allaah as much as you are able} [Quran 64: 16]
Therefore, an individual whose tongue is injured so that he cannot utter the letters or that the utterance harms him is not obliged to recite with his tongue and he may recite it with his heart.
Allaah Knows best.
