al-Saʿdī
Al-Saʿdī explains that Allah here lists His favours and proofs of His power to establish the resurrection: He built above us seven firm, mighty heavens, perfectly fashioned and held aloft without flaw, and set within them a brilliant, intensely burning lamp—the sun—which gives light and heat and ripens the produce of the earth. He then sends down from the rain-laden clouds abundant pouring water, by which He brings forth grain that people and animals eat, herbage, and densely interlaced gardens of trees. He notes that the One able to create all this from nothing is surely able to raise the dead, so these verses are at once a demonstration of mercy and an argument for the Day of Reckoning.
