Allah also says: {There has certainly come to you a Messenger from among yourselves. Grievous to him is what you suffer; [he is] concerned over you and is kind and merciful towards the believers.} [Ch. 9, Verse 128]
Allah also says: {And We have not sent you, [O Muhammad], except as a mercy to the worlds.} [Ch. 21, Verse 107]
Muhammad (pbuh), the gifted mercy
He is Muhammad ibn Abdullah, the final Prophet and Messenger. Allah, the Exalted, sent him with the religion of Islam to all mankind, to guide them to all that is good, and the greatest of good is Tawhid (monotheism; belief in the Oneness of Allah), and to warn them against all that is evil, and the worst of evil is Shirk (polytheism; associating partners with Allah).
It is an obligation to obey his orders, believe what he said, avoid what he forbade or warned against, and worship Allah only in the manner that he prescribed.
His message and the message of all the prophets before him was to call for the worship of Allah alone without a partner.
Some of his traits (pbuh):
Honesty, mercy, forbearance, patience, bravery, generosity, good manners, fairness, modesty, and forgiveness.
