وَجَعَلَ فِيهَا رَوَٰسِىَ مِن فَوْقِهَا وَبَـٰرَكَ فِيهَا وَقَدَّرَ فِيهَآ أَقْوَٰتَهَا فِىٓ أَرْبَعَةِ أَيَّامٍ سَوَآءً لِّلسَّآئِلِينَ
41:10
He placed therein (i.e. the earth) firm mountains from above it, and He blessed it, and measured therein its sustenance (for its dwellers) in four Days equal (i.e. all these four 'days' were equal in the length of time), for all those who ask (about its creation). - Muhammad Taqi-ud-Din al-Hilali and Muhammad Muhsin Khan (English)
