i know what u mean, and in some cases allah asks questions to the angels even though he already knows the answer. And there are several hadiths and quranic verses related to this topic but please you shouldn't ask questions like this "why does allah do this" we do not question allah. Allah is all-knowing and he knows best whereas we do not know. Our knowledge is too little therefore we question why allah does that. I don't know the answer to this. Maybe it is better when verses are revealed bit by bit for better understanding.
