Commentary on Tafsir al-Jalalayn: ((Dahuran)) is the verbal noun of dahara, meaning he drove him away and banished him.

Dahuran means driving away and banishing. As the author stated, it is a ma'ful lahu, meaning for the sake of the driving away. How many types of ma'ful (objects) are there? There are five: the absolute object (ma'ful mutlaq), the object with which (ma'ful bihi), the object in which (ma'ful fihi), the object for the sake of which (ma'ful lahu), and the object with which (ma'ful ma'ahu). These are the five, and their examples are: "I struck a blow at Abu 'Amr on the day he came, and I traveled along the Nile out of fear of your punishment for me"
I repeat: "I struck a blow at Abu 'Amr on the day he came, and I traveled along the Nile out of fear of your punishment for me"
These are five examples. "I struck a blow" — what is this? The absolute object (ma'ful mutlaq). "Abu 'Amr" — the object with which (ma'ful bihi). "On the day he came" — the object in which (ma'ful fihi). "And I traveled along the Nile" — with it (ma'ful ma'ahu). "Out of fear of your punishment for me" — the object for the sake of which (ma'ful lahu). He says: and for them in the Hereafter is a persistent punishment, meaning continuous. So they are punished in this world with these meteors, and they are punished in the Hereafter with the continuous punishment, because the devils are among the companions of the Fire.
