Al-Hijr - ১৫:২১

وَإِن مِّن شَيْءٍ إِلاَّ عِندَنَا خَزَائِنُهُ وَمَا نُنَزِّلُهُ إِلاَّ بِقَدَرٍ مَّعْلُومٍ
[15:21]
And there is not a thing but with Us are the treasures of it, and We do not send it down but in a known measure.
And there is not a thing but its (sources and) treasures (inexhaustible) are with Us; but We only send down thereof in due and ascertainable measures.
And there is not a thing but with Us are the stores thereof. And we send it not down save in appointed measure.
