The word(s) "demanding" appears 2 time(s) in 2 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) Among the People of the Book are some who, if entrusted with a hoard of gold, will (readily) pay it back; others, who, if entrusted with a single silver coin, will not repay it unless thou constantly stoodest demanding, because, they say, "there is no call on us (to keep faith) with these ignorant (Pagans)." but they tell a lie against Allah, and (well) they know it.

(2) (David) said: "He has undoubtedly wronged thee in demanding thy (single) ewe to be added to his (flock of) ewes: truly many are the partners (in business) who wrong each other: Not so do those who believe and work deeds of righteousness, and how few are they?"... and David gathered that We had tried him: he asked forgiveness of his Lord, fell down, bowing (in prostration), and turned (to Allah in repentance).
