Is it obligatory to believe in all the angels and the messengers?

Question:
Our brother, the questioner Ibrahim Abu Hamid, may Allah reward him with good, sent a set of questions. He says regarding creed: "Your Eminence! Is it obligatory to believe in all the angels and the messengers? And what is the ruling on one who does not love some of them?"

Answer:
It is obligatory for every believer to believe in Allah, His angels, His books, and His messengers. This is one of the foundations of faith. One must believe in the angels, even if he does not know their names. That is, he must believe in those who are named, such as Jibril, Mika'il, and Israfil, and he must believe in all of them, even if he does not know their names. He must believe that Allah has angels about whom the Messenger of Allah (peace and blessings be upon him) informed us, regarding their obedience to Him and their execution of His commands, including Jibril, Mika'il, the bearers of the Throne, and others.
And he believes in all the messengers, even if he does not know their names. He believes that Allah sent messengers and that they conveyed the messages. Whoever Allah named, he believes in him, such as Nuh, Ibrahim, Musa, Isa, Dawud, and Sulayman. Whoever Allah named, he believes in him, and whoever was not named, he believes that Allah has messengers, even if he does not know their names. Just as he believes in their seal, Muhammad (peace and blessings be upon him), and that he is the Messenger of Allah to all, to all of the two groups of jinn and humans, and that he is the seal of the prophets. It is necessary to believe in this. Whoever does not believe in this is a disbeliever. We ask Allah for safety.
