The word(s) "reason" appears 16 time(s) in 14 verse(s) in Quran in Mohsin Khan translation.

(11) Say: "O people of the Scripture (Jews and Christians)! Do you criticize us for no other reason than that we believe in Allah, and in (the revelation) which has been sent down to us and in that which has been sent down before (us), and that most of you are Fasiqun [rebellious and disobedient (to Allah)]?"

(12) You see many of them taking the disbelievers as their Auliya' (protectors and helpers). Evil indeed is that which their ownselves have sent forward before them; for that (reason) Allah's Wrath fell upon them, and in torment they will abide.

(13) (Allah) said: "O Iblis (Satan)! What is your reason for not being among the prostrators?"

(14) "I will surely punish him with a severe torment, or slaughter him, unless he brings me a clear reason."
