What is dealt with briefly at one place is expanded in some other place. Since the belief in the creation of Allah such as angels and jinn is fundamental to the Islamic belief, it is worthwhile to know who they are and what their nature is. Among the things of which he informed us is that Allah Most High has created angels that are pure spirits, neither masculine nor feminine, and created jinn, fiery beings that can assume various forms. The difference between jinn and angels is that angels are created of light, while jinn are created of fire. Angels do not commit disobedience, while jinn include both the obedient and the disobedient, both believer and unbeliever, the rebellious of them being called devils.
Angels live in the heavens and earth, while jinn live only on earth.
Angels are not called to account on the Day of Judgement, but rather enter paradise, and whoever disparages one of them has committed unbelief. They rejoice at whoever visits the ill or seeks religious knowledge, out of pleasure with what he is doing. They both are distinct entities created by Allah. This is because knowledge of the reports of men of the past and of contemporaneous views of men of the present do not reach the one who has not witnessed them nor lived in their times except through the accounts of reporters and the transmission of transmitters, to the exclusion of rational deduction and mental inference. Hence, if I mention in this book a report about some men of the past, which the reader of listener finds objectionable or worthy of censure because he can see no aspect of truth nor any factual substance therein, let him know that this is not to be attributed to us but to those who transmitted it to us and we have merely passed this on as it has been passed on to us.
