He who gives plenty letting things expand.
“Make not thy hand tied (like a niggard’s) to thy neck, nor stretch it forth to its utmost reach, so that thou become blameworthy and destitute. Verily thy Lord doth PROVIDE SUSTENANCE IN ABUNDANCE for whom
He pleaseth, and He provideth in a just measure: for He doth know and regard all His servants. Kill not your children for fear of want: We shall provide sustenance for them as well as for you verily the killing of them is a
great sin. Nor come nigh to adultery: for it is a shameful (deed) and an evil, opening the road (to other evils)”
(17:29…32) The Holy Quran
