Al-Jinn 72:13

Waanna lamma samiAAnaalhuda amanna bihi faman yu/min birabbihifala yakhafu bakhsan wala rahaqa

And when we heard the guidance [i.e., the Qur’ān], we believed in it. And whoever believes in his Lord will not fear deprivation or burden.

and that when we heard the Guiding Discourse, we believed in it; so if one believes in his Lord, he will have no fear of either any curtailment (in his reward) or any excess (in his punishment),
