The word(s) "simply" appears 3 time(s) in 3 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) "But thou dost wreak thy vengeance on us simply because we believed in the Signs of our Lord when they reached us! Our Lord! pour out on us patience and constancy, and take our souls unto thee as Muslims (who bow to thy will)!

(2) They said: "If he steals, there was a brother of his who did steal before (him)." But these things did Joseph keep locked in his heart, revealing not the secrets to them. He (simply) said (to himself): "Ye are the worse situated; and Allah knoweth best the truth of what ye assert!"

(3) O ye who believe! Take not my enemies and yours as friends (or protectors),- offering them (your) love, even though they have rejected the Truth that has come to you, and have (on the contrary) driven out the Prophet and yourselves (from your homes), (simply) because ye believe in Allah your Lord! If ye have come out to strive in My Way and to seek My Good Pleasure, (take them not as friends), holding secret converse of love (and friendship) with them: for I know full well all that ye conceal and all that ye reveal. And any of you that does this has strayed from the Straight Path.
