Seeing the angels and the jinn, in a form other than their true form, is possible. As for suggesting that only children can see that, we do not know of any text which speaks of that. This is a matter of the unseen, and we cannot say anything about it except on the basis of evidence, and there is no evidence to deny or affirm that.

Islamic `Aqidah is not a theoretical and philosophical method; action is an essential part of this `Aqidah. Hence the Ahl As-Sunnah agreed that faith consists of words and deeds, or speaking with the tongue, believing in the heart and acting with the physical faculties. With regard to applying this `Aqidah in real life, this is done by learning it, propagating it, calling others to it, and refuting those who go against it with wisdom and beautiful preaching.

There are 10 things that take one out of the fold of Islam: 1. Associating others in worship with Allah. 2. Whoever sets up intermediaries between himself and Allah and calls upon them. 3. Whoever does not regard the polytheists as disbelievers. 4. Whoever believes that anything other than the teaching of the Prophet is more complete than his teachings. 5. Whoever hates any part of that which the Prophet brought. 6. Whoever makes fun of anything in the religion of the Prophet. 7. Witchcraft – including spells to turn one person against another or to make someone love another. 8. Supporting the polytheists and helping them against the Muslims. 9. Whoever believes that some people are allowed to operate outside the law of Muhammad. 10. Turning away from the religion of Allah, not learning it and not acting in accordance with it.

Allah, may He be exalted, may be asked for the purpose of learning with humility, or He may be asked for the purpose of seeking guidance and knowledge, but He is not to be questioned by way of objection or disapproval of anything that He does, may He be glorified. The question of the angels was a question that was aimed at learning, for they were aware of the rights of their Lord, and they glorified and praised Him, for they are the ones who do not disobey Allah in what He commands them, and they do as they are commanded.
