What does « Jism » mean in the Quran?

And their prophet said to them, "Indeed, Allah has sent to you Saul as a king." They said, "How can he have kingship over us while we are more worthy of kingship than him and he has not been given any measure of wealth?" He said, "Indeed, Allah has chosen him over you and has increased him abundantly in knowledge and stature. And Allah gives His sovereignty to whom He wills. And Allah is all-Encompassing [in favor] and Knowing."

And when you see them, their forms please you, and if they speak, you listen to their speech. [They are] as if they were pieces of wood propped up - they think that every shout is against them. They are the enemy, so beware of them. May Allah destroy them; how are they deluded?
