Belief In The Messengers To believe in the Messengers means to believe with certainty that Allah sent a Messenger to each nation, calling them to worship Allah alone, without associating partners with Him, and calling them to disbelieve in all that is worshipped other than Him. We must also believe that every one of the Messengers is truthful, guided, righteous, and obedient to Allah and that they conveyed all that Allah sent them with: they neither hid any part of the message nor did they change any part of it. Allah Almighty says:
Are the Messengers charged with anything but to clearly convey the Message? And verily, We have sent among every Ummah (community, nation) a Messenger (proclaiming): "Worship Allah, and avoid the Taghut (all false deities)." Then of them were some whom Allah guided and of them were some upon whom the straying was justified. So, travel through the land and see what was the end of those who denied (the truth). (Surah An-Nahl 16: 35-36) Some of the Messengers were better than others:
Those Messengers! We preferred some of them to others; to some of them Allah spoke (directly); others He raised to degrees (of honor); and to 'Iesa, the son of Maryam, We gave clear proofs and evidences, and supported him with Ruhul- Qudus [Jibril (Alayhi Salam)] (Surah Al-Baqarah 2: 253) The best of the Messengers are five known as Ulul-'Azm, or the Messengers of firm will: Nuh, Ibrahim, Musa, 'Iesa, and Muhammad, may the peace and blessings of Allah be upon them all, and the best of these five is Muhammad (Sallallahu Alayhi wa Sallam).
To have belief in all of the Messengers is obligatory; whoever disbelieves in one from them, then he has not only disbelieved in them all, but he has also disbelieved in the One Who sent them -- Allah, Allah Almighty says:
Verily, those who disbelieve in Allah and His Messengers and wish to make distinction between Allah and His Messengers saying, "We believe in some but reject others," and wish to adopt a way in between. They are in truth disbelievers. And We have prepared for the disbelievers a humiliating torment. And those who believe in Allah and His Messengers and make no distinction between any of them (Messengers), We shall give them their rewards, and Allah is Ever Oft Forgiving, Most Merciful. (Surah An-Nisa’ 4: 150-152) We must believe in the Messengers in general, meaning that we believe in those that we know of and those that we don't know of. So, we must specifically believe in those Messengers that Allah named, and we must believe that Allah sent Messengers other than the ones He named to us:
And, indeed We have sent Messengers before you; of some of them We have related to you their story and of some We have not related to you their story. (Surah Ghafir 40:78) It is not a part of faith to raise them above the status that Allah gave to them, for they are human beings and His creatures. They are distinct in that Allah chose them and prepared them to carry His Message. Their nature is that of man; they have no share in the qualities specific to godhood, so they don't know the information of the unseen, except for those matters that Allah has informed them about. Allah ordered Muhammad (Sallallahu Alayhi wa Sallam) to convey to his nation:
Say: "I am only a human being like you. It is inspired in me that your Ilah (God) is One Ilah. (Surah Fussilat 41:6)
Say: "I don't tell you that with me are the treasures of Allah, nor (that) I know the unseen; nor do I tell you that I am an angel. I but follow what is revealed to me by inspiration.” (Surah Al-An’am 6: 50) The Definition of Nabi (Prophet) and Rasul (Messenger) Nabi in the Arabic language: It is taken from the word Naba'a, which means news or information. A Prophet is called a Nabi because he informs us about Allah Almighty - i.e., he conveys to us His Orders and revelation. A Prophet is perhaps also called Nabi because Allah informed him.
Rasul in the Arabic language: Rasul is taken from Irsal, which means direction. Therefore the Messengers are thus named because they are directed from Allah. Allah Almighty says:
Then We sent Our Messengers in succession,(Surah Al-Mu’minun 23: 44)
The Difference between a Nabi (Prophet) And a Rasul (Messenger) A Rasul is a man who is inspired with a new Shari'ah or set of laws, and he is sent to a transgressing people, conveying to them Allah's Message - for example, the Messengers of firm will (Ulul-'Azm).
A Nabi is a man who is inspired with a message, but the message is to follow the Shari'ah of those who preceded him; he is sent to apply a previously sent Shari'ah (set of laws) - for example, the Prophets from the Children of Israel that came after Musa, (Alayhi Salam). Allah Almighty says:
Verily, We did send down the Tawrah, therein was guidance and light, by which the Prophets, who submitted themselves to Allah's Will. (Surah Al-Ma’idah 5: 44) Prophethood is a Blessing granted by Allah Prophethood is a blessing that Allah bestows according to His choice:
Allah chooses Messengers from angels and from men. (Surah Al-Hajj 22.75)
Therefore Prophethood is not a goal that is achieved through man's striving or working; rather, it is a high and special rank for which Allah chooses - purely by His grace - whomsoever He pleases from His creation. He prepares them to carry the message, He protects them from the effects of the devils, and He protects them from Shirk, as a favor and mercy from Him, not from the efforts they expended. It is a blessing and favor from Allah; He says:
Those were they to whom Allah bestowed His grace from among the Prophets, of the offspring of Adam, and of those whom We carried (in the ship) with Nuh, and of the offspring of Ibrahim and Israel and from among those whom We guided and chose. (Surah Maryam 19:58) Allah said to Musa:
I have chosen you above men by My Messages, and by My speaking (to you).
(Surah Al-A’raf 7:144)
And Allah said, relating the words of Ya'qub to his son Yusuf, (Alayhuma Salam)
Thus will your Lord choose you. ((Surah Yusuf 12: 6)
All of the above verses clearly indicate that Prophethood is not achieved by greatness or by actions; rather, it is a blessing and mercy from Allah. He chooses men for that ranking by His Knowledge and Wisdom; it is a ranking that is not achieved by those who wish for it or work for it.
