Surah Fussilat, ayah 10

وَجَعَلَ فِيهَا رَوَٰسِيَ مِن فَوۡقِهَا وَبَٰرَكَ فِيهَا وَقَدَّرَ فِيهَآ أَقۡوَٰتَهَا فِيٓ أَرۡبَعَةِ أَيَّامٖ سَوَآءٗ لِّلسَّآئِلِينَ ١٠

Waja'ala fīhā rawāsiya min fawqihā wabāraka fīhā waqaddara fīhā aqwātahā fī arba'ati ayyāmin sawā'al lis-sā'ilīn

And He placed on it [i.e., the earth] firmly set mountains over its surface, and He blessed it and determined therein its [creatures'] sustenance in four days without distinction¹³⁸⁴ - for [the information of] those who ask.
