The word(s) "responsibility" appears 4 time(s) in 4 verse(s) in Quran in Mohsin Khan translation.

(1) And divorced women shall wait (as regards their marriage) for three menstrual periods, and it is not lawful for them to conceal what Allah has created in their wombs, if they believe in Allah and the Last Day. And their husbands have the better right to take them back in that period, if they wish for reconciliation. And they (women) have rights (over their husbands as regards living expenses) similar (to those of their husbands) over them (as regards obedience and respect) to what is reasonable, but men have a degree (of responsibility) over them. And Allah is All-Mighty, All-Wise.

(2) And upon Allah is the responsibility to explain the Straight Path . But there are ways that turn aside (such as Paganism, Judaism and Christianity). And had He willed, He would have guided you all (mankind).

(3) Those who are faithfully true to their Amanat (all the duties which Allah has ordained, honesty, moral responsibility and trusts) and to their covenants;

(4) Truly, We did offer Al-Amanah (the trust or moral responsibility or honesty and all the duties which Allah has ordained) to the heavens and the earth, and the mountains, but they declined to bear it and were afraid of it (i.e. afraid of Allah's Torment). But man bore it. Verily, he was unjust (to himself) and ignorant (of its results).
