The word(s) "constrained" appears 2 time(s) in 2 verse(s) in Quran in Saheeh International translation.

(1) Then would you possibly leave [out] some of what is revealed to you, or is your breast constrained by it because they say, "Why has there not been sent down to him a treasure or come with him an angel?" But you are only a warner. And Allah is Disposer of all things.

(2) And We already know that your breast is constrained by what they say.
