The word(s) "incumbent" appears 7 time(s) in 6 verse(s) in Quran in Muhammad Pickthal translation.

(1) Mothers shall suckle their children for two whole years; (that is) for those who wish to complete the suckling. The duty of feeding and clothing nursing mothers in a seemly manner is upon the father of the child. No-one should be charged beyond his capacity. A mother should not be made to suffer because of her child, nor should he to whom the child is born (be made to suffer) because of his child. And on the (father's) heir is incumbent the like of that (which was incumbent on the father). If they desire to wean the child by mutual consent and (after) consultation, it is no sin for them; and if ye wish to give your children out to nurse, it is no sin for you, provide that ye pay what is due from you in kindness. Observe your duty to Allah, and know that Allah is Seer of what ye do.

(2) Forgiveness is only incumbent on Allah toward those who do evil in ignorance (and) then turn quickly (in repentance) to Allah. These are they toward whom Allah relenteth. Allah is ever Knower, Wise.

(3) Whoso migrateth for the cause of Allah will find much refuge and abundance in the earth, and whoso forsaketh his home, a fugitive unto Allah and His messenger, and death overtaketh him, his reward is then incumbent on Allah. Allah is ever Forgiving, Merciful.

(4) Then shall We save Our messengers and the believers, in like manner (as of old). It is incumbent upon Us to save believers.

(5) He said: This is a right course incumbent upon Me:

(6) Verily We sent before thee (Muhammad) messengers to their own folk. Then we took vengeance upon those who were guilty (in regard to them). To help believers is ever incumbent upon Us.
