The word(s) "deaf" appears 21 time(s) in 20 verse(s) in Quran in Muhammad Pickthal translation.

(11) And who doth greater wrong than he who hath been reminded of the revelations of his Lord, yet turneth away from them and forgetteth what his hands send forward (to the Judgment)? Lo! on their hearts We have placed coverings so that they understand not, and in their ears a deafness. And though thou call them to the guidance, in that case they can never be led aright.

(12) Say (O Muhammad, unto mankind): I warn you only by the Inspiration. But the deaf hear not the call when they are warned.

(13) And those who, when they are reminded of the revelations of their Lord, fall not deaf and blind thereat.

(14) Lo! thou canst not make the dead to hear, nor canst thou make the deaf to hear the call when they have turned to flee;

(15) For verily thou (Muhammad) canst not make the dead to hear, nor canst thou make the deaf to hear the call when they have turned to flee.

(16) And when Our revelations are recited unto him he turneth away in pride as if he heard them not, as if there were a deafness in his ears. So give him tidings of a painful doom.

(17) And they say: Our hearts are protected from that unto which thou (O Muhammad) callest us, and in our ears there is a deafness, and between us and thee there is a veil. Act, then. Lo! we also shall be acting.

(18) And if We had appointed it a Lecture in a foreign tongue they would assuredly have said: If only its verses were expounded (so that we might understand)? What! A foreign tongue and an Arab? - Say unto them (O Muhammad): For those who believe it is a guidance and a healing; and as for those who disbelieve, there is a deafness in their ears, and it is blindness for them. Such are called to from afar.

(19) Canst thou (Muhammad) make the deaf to hear, or canst thou guide the blind or him who is in error manifest?

(20) Such are they whom Allah curseth so that He deafeneth them and maketh blind their eyes.
