A consensus has been formed especially among the followers of religions that there have always been some who see and converse with angels jinn. Satan and other spirit beings. So the establishment of the existence of a single individual is enough to prove the existence of the whole species of spirit beings. Had the angels not existed and if a single angel had not been seen or the existence of one or numerous individual angels not been established through observation would it have been possible for such a general belief to continue and had this belief not been based on strong evidences could it have come down to the present time in spite of the changing of ideas and beliefs along with the passage of time? Therefore we can conclude that the religious belief in the existence of the angels and other spirit beings is based on the experiences which the Prophets and some other godly persons have had with them and this has been narrated by reliable sources.
