12 Preface لَهُ مَقاليدُ السَّماواتِ وَالأَرضِ ۖ يَبسُطُ الرِّزقَ لِمَن يَشاءُ وَيَقدِرُ ۚ إِنَّهُ بِكُلِّ شَيءٍ عَليمٌYusuf AliTo Him belong the keys of the heavens and the earth: He enlarges and restricts.1 The Sustenance to whom He will: for He knows full well all things.“Sustenance”, here as elsewhere, stands for all things that support every phase of life, physical, social, intellectual, or spiritual. Cf. 10:59, n. 1447. The source of all gifts is God; His bounty is inexhaustible, and He gives to all; but He does not give to all in the same measure, because, out of the fullness of His knowledge and wisdom, He can judge best what is best for any of His creatures (see also n. 4554 and n. 4740).
