(34) Allah is he Who sends forth the winds so they raise a cloud, then He spreads it forth in the sky as He pleases, and He breaks it up so that you see the rain coming forth from inside it; then when He causes it to fall upon whom He pleases of His servants, lo! they are joyful

(35) O my son! surely if it is the very weight of the grain of a mustard-seed, even though it is in (the heart of) rock, or (high above) in the heaven or (deep down) in the earth, Allah will bring it (to light); surely Allah is Knower of subtleties, Aware;

(36) Surely Allah is He with Whom is the knowledge of the hour, and He sends down the rain and He knows what is in the wombs; and no one knows what he shall earn on the morrow; and no one knows in what land he shall die; surely Allah is Knowing, Aware.

(37) And a sign to them is the dead earth: We give life to it and bring forth from it grain SQ they eat of it.

(38) And with them shall be those who restrain the eyes, having beautiful eyes;

(39) And with them shall be those restraining their eyes, equals in age.

(40) And He it is Who sends down the rain after they have despaired, and He unfolds His mercy; and He is the Guardian, the Praised One.
