The word(s) "ears" appears 135 time(s) in 124 verse(s) in Quran in Abdullah Yusuf Ali translation.

(51) And who doth more wrong than one who is reminded of the Signs of his Lord, but turns away from them, forgetting the (deeds) which his hands have sent forth? Verily We have set veils over their hearts lest they should understand this, and over their ears, deafness, if thou callest them to guidance, even then will they never accept guidance.

(52) Behold, Moses said to his attendant, "I will not give up until I reach the junction of the two seas or (until) I spend years and years in travel."

(53) They ask thee concerning Zul-qarnain. Say, "I will rehearse to you something of his story."

(54) Those were some of the prophets on whom Allah did bestow His Grace,- of the posterity of Adam, and of those who We carried (in the Ark) with Noah, and of the posterity of Abraham and Israel of those whom We guided and chose. Whenever the Signs of (Allah) Most Gracious were rehearsed to them, they would fall down in prostrate adoration and in tears.

(55) When Our Clear Signs are rehearsed to them, the Unbelievers say to those who believe, "Which of the two sides is best in point of position? Which makes the best show in council?"

(56) "Behold! thy sister goeth forth and saith, 'shall I show you one who will nurse and rear the (child)?' So We brought thee back to thy mother, that her eye might be cooled and she should not grieve. Then thou didst slay a man, but We saved thee from trouble, and We tried thee in various ways. Then didst thou tarry a number of years with the people of Midian. Then didst thou come hither as ordained, O Moses!

(57) He knows what (appears to His creatures as) before or after or behind them: but they shall not compass it with their knowledge.

(58) Do they not travel through the land, so that their hearts (and minds) may thus learn wisdom and their ears may thus learn to hear? Truly it is not their eyes that are blind, but their hearts which are in their breasts.

(59) Yet they ask thee to hasten on the Punishment! But Allah will not fail in His Promise. Verily a Day in the sight of thy Lord is like a thousand years of your reckoning.

(60) That is because Allah merges night into day, and He merges day into night, and verily it is Allah Who hears and sees (all things).
