What does it mean to believe in Allaah?
It means: 1- To believe in Allaahs total Perfection and Uniqueness. 2- To believe in the Angels. We must love them all in the same way, we cannot hate an Angel; for example, it is forbidden to hate Michael who is given the charge of Rain and the vegetation of the Earth or Gabriel, who is entrusted with Revelation (i.e. he brings down the Scriptures to the prophets, may Allaah exalt their mention). 3- To believe in Allaah’s books revealed to His Prophets, may Allaah exalt their mention, taking into consideration that all of these books have either disappeared or changed, except the last divine book, the Quran. 4- To believe in His Prophets, may Allaah exalt their mention, because they are His Messengers and He sent them. We cannot pick and choose, a Muslim must believe in all the Prophets of Allaah, may Allaah exalt their mention.
