The word(s) "blindly" appears 9 time(s) in 9 verse(s) in Quran in Mohsin Khan translation.

(1) Allah mocks at them and gives them increase in their wrong-doing to wander blindly.

(2) And We shall turn their hearts and their eyes away (from guidance), as they refused to believe therein for the first time, and We shall leave them in their trespass to wander blindly.

(3) Whomsoever Allah sends astray, none can guide him; and He lets them wander blindly in their transgressions.

(4) And were Allah to hasten for mankind the evil (they invoke for themselves and for their children. while in a state of anger) as He hastens for them the good (they invoke) then they would have been ruined. So We leave those who expect not their meeting with Us, in their trespasses, wandering blindly in distraction. (Tafsir At-Tabari)

(5) Verily, by your life (O Muhammad صلى الله عليه و سلم), in their wild intoxication, they were wandering blindly.

(6) Say (O Muhammad صلى الله عليه وسلم): "I warn you only by the revelation (from Allah and not by the opinion of the religious scholars and others). But the deaf (who follow the religious scholars and others blindly) will not hear the call, (even) when they are warned [i.e. one should follow only the Qur'an and the Sunnah (legal ways, orders, acts of worship, and the statements of Prophet Muhammad صلى الله عليه وسلم, as the companions of the Prophet صلى الله عليه وسلم did)] .

(7) And though We had mercy on them and removed the distress which is on them, still they would obstinately persist in their transgression, wandering blindly.

(8) Verily, those who believe not in the Hereafter, We have made their deeds fair-seeming to them, so that they wander about blindly.

(9) And whosoever turns away blindly from the remembrance of the Most Gracious (Allah) (i.e. this Qur'an and worship of Allah), We appoint for him Shaitan (Satan - devil) to be a Qarin (a companion) to him.
