Muslims believe in all Rusul (Messengers) that Allah (God) had sent for the guidance of mankind. These Rusul (Messengers) were sent to different places at different times. All of these Rusul (Messengers) had brought the same Message of Allah (God).
Each Rasul (Messenger) faithfully delivered the Message of Allah (God) to his people and presented a perfect way of life as example. These Rusul (Messengers) invited people to the path of Allah (God).
People altered and modified the Messages of Allah (God) for their own benefits and whenever it happened, Allah (God) sent His Message over through another Rasul (Messenger).

All Rusul (Messengers) performed the same job of delivering Messages of Allah (God) to mankind. Muslims respect all Rusul (Messengers) of Allah (God) equally and do not consider any Rasul (Messenger) better or superior than others. Muslims also believe that all Rusul (Messengers) were normal human beings, who were picked-up by Allah (God) at various ages of their lives for this responsibility. Allah (God) gave special powers of performing miracles to some of His Rusul (Messengers).

The first Rasul (Messenger) of Allah (God) was Adam A (Adam) and the last one was Muhammad S. Although, most of the Rusul (Messengers) from the three major religions Islam, Christianity and Judaism were from Middle Eastern origins; Allah (God) had sent His Rusul (Messengers) to each and every part of the world.

Names of twenty-five Rusul (Messengers) of Allah (God) are mentioned in the Qur-an. Twenty-one of these Rusul (Messengers) are also mentioned in the Bible:

Believing in all of Allah (God)’s Rusul (Messengers) is a part of the basic Iman (Belief) of Muslims.

While Muslims believe in all the Rusul (Messengers), they do not believe in the existing texts of the Messages brought by them, because that was deliberately changed by their followers to suit them.

Muslims also believe that Muhammad S was the last Rasul (Messenger) of Allah (God), and He would not send any more Messages or Messengers to mankind. The Messenger of Allah, Muhammad S delivered the Qur-an, the final version of the Message of Allah (God). Allah (God) has promised to protect it till the end of the world.

Muslims believe that the life of the Messenger of Allah, Muhammad S is a perfect example of leading one’s life strictly according to the Commandments of Allah (God). Detailed life-sketches of Rusul (Messengers) of other religions are not available.
Complete details are only available on all aspects of the life of the Messenger of Allah, Muhammad S. His life was like an open book where each and every detail was available.

Muhammad S taught what Allah (God) taught him, a way of life that pleases Allah (God). Though Muhammad S lived fourteen millenniums ago, those fundamental principles remain the same for ever.

Say: "I tell you not that with me are the treasures of Allah, nor do I know what is hidden, nor do I tell you I am an angel. I but follow what is revealed to me." Say: "Can the blind be held equal to the seeing?" Will you then consider not?
Surah (Chapter) Al-An’am (The Cattle) The Qur-an 6:50

The Messenger of Allah, Muhammad S lived his life according to the Islamic principles and Allah (God) has commanded Muslims to follow him.

He who obeys the Messenger (Muhammad S), has indeed obeyed Allah, but he who turns away, then We have not sent you (O Muhammad S) as a watcher over them.
Surah (Chapter) An-Nisa” (The Woman) The Qur-an 4:80

The Messenger of Allah, Muhammad S commands ultimate respect from Muslims.
