"And He has created you in stages." The interpretation of Qatadah: Meaning: a drop of sperm, then a clot, then a lump of flesh, then bone, then flesh.

Muhammad said: "(In stages)," meaning: stage after stage; He moved you from one state to another, and this is the meaning of the statement of Qatadah. And His saying: "Expect," means: you fear. Similar to it is the saying of the poet:

(Their abode is the Essence of the God, and their religion is… upright, so they do not fear other than the consequences.)

Meaning: They do not fear anything except the final outcomes of deeds.
