“fulfill”
in Edition Clear Qur'an by Talal Itani / Al-An'aam (The Cattle)
6:60It is He Who takes you by night, and He knows what you earn by day. Then He raises you up in it, until a fixed term is fulfilled. Then to Him is your return, then He will inform you of what you used to do.
6:152And do not come near the property of the orphan, except with the best intentions, until he reaches maturity. And give full weight and full measure, equitably. We do not burden any soul beyond its capacity. And when you speak, be fair, even if it concerns a close relative. And fulfill your covenant with God. All this He has enjoined upon you, so that you may take heed.

Those who spend their wealth by night and day, privately and publicly, will receive their reward from their Lord. They have nothing to fear, nor shall they grieve.
