Al-Isra 17:29

Wala tajAAal yadaka maghloolatan ilaAAunuqika wala tabsutha kulla albastifataqAAuda malooman mahsoora

And do not make your hand [as] chained to your neck or extend it completely and [thereby] become blamed and insolvent.

And do not keep your hand tied to your neck, nor extend it to the full extent, lest you should be sitting reproached, empty-handed.
