Who is the messenger of Islam?

He is Muhammad ibn Abdullah, the final Messenger. Allah says: (Muhammad is not the father of any man among you, but he is the Messenger of Allah and the last of the Prophets.) [ 33:40 ]

Allah did not send him specifically to the Arabs, but rather to all mankind. Allah says: (And We have not sent you [O Muhammad ] except comprehensively as a giver of glad tidings and a Warner to all mankind.) [ 34:28 ]

Allah sent him so that the entire creation may achieve true happiness, and to show them the path of truth, goodness and to warn them against falsehood and evil. Allah said: (And We have only sent you [O Muhammad ] as a mercy for the worlds.) [ 21:107 ]

Even before he received revelation, he was known amongst his people as ‘The Trustworthy’, and they would entrust him with their belongings when they set off on a journey. He was also known as ‘The Truthful’ due to the truthfulness they knew of him. They never found him making excuses, lying, acting treacherously nor deceivingly. He always desired good for others.

He received his first revelation at the age of forty, and he informed his wife Khadeejah saying: “Indeed I fear for myself.” Khadeejah replied, “No, by Allah! Allah will never humiliate you. Indeed you maintain ties of kinship, you shoulder the problems of others, you give wealth to those who do not have it, you honor and feed your guest, and you give support in times of true calamity.” ( Bukhari )

He remained in Mecca for thirteen years thereafter, calling people to believe in the true Monotheism of Islam. He then migrated to the city of Madinah and called its inhabitants to Islam, which they accepted. There, Allah revealed to him the remaining legislations of the Deen. He returned and conquered Mecca eight years after his migration, and he died at the age of sixty-three after Allah revealed to him the entire Qur’an. All the legislations of the Deen were perfected and completed and the entirety of the Arabian peninsula had accepted Islam.

He was the most perfect of mankind in respect to his creation and manners.

what they say about muhammad ?

The German poet Goethe said: ‘I looked into history for a human paradigm and found it to be in Muhammad (s) ;Annie Besant in ‘The Life and Teachings of Mohammad,’ said:
‘It is impossible for anyone who studies the life and character of the great Prophet of Arabia, who knew how he taught and how he lived, to feel anything but reverence for the mighty Prophet, one of the great messengers of the Supreme. And although in what I put to you I shall say many things which may be familiar to many, yet I myself feel, whenever I reread them, a new way of admiration, a new sense of reverence for that mighty Arabian teacher.’
