The word(s) "refused" appears 12 time(s) in 12 verse(s) in Quran in Mohsin Khan translation.

(11) And (remember) when We said to the angels: "Prostrate yourselves to Adam." They prostrated themselves (all) except Iblis (Satan) he refused.

(12) And if any of your wives have gone from you to the disbelievers, (as apostates and you asked them to return back your Mahr but they refused) - then you went out for a Ghazwah (military expedition) (against them and) gained booty; then pay from that booty to those whose wives have gone, the equivalent of what they had spent (on their Mahr ). And fear Allah in Whom you believe.
