Allah provides several proofs of His ability to resurrect mankind from the dead based on His creation of astonishing things in this world. He mentions making the earth stable, creating mountains as pegs to stabilize the earth, creating mankind in different pairs and categories from one essence, making sleep a means of rest, making night a cover and day a time of livelihood, building seven strong heavens and creating the sun as a shining lamp. Allah sends down abundant water from rain clouds to produce vegetation and crops. Through these signs, Allah demonstrates His power to resurrect mankind for judgment as He wills.
