One of the loftiest graces Allah] has bestowed upon our Ummah was sending Prophet Muhammad (SAWS) as a messenger and a guide. In the Noble Qur’an Allah says what can be translated as “Indeed there has already come to you a Messenger from (among) yourselves. Mighty (i.e., burdensome) to him is whatever distresses you. Most eager is he for your (welfare), to the believers (he is) constantly compassionate, constantly merciful.” ( 9: 128)
Scholar Sa’di indicated that “this bounty is the most valuable of Allah’s bounties bestowed to his worshippers: He sent them this noble Prophet to take them out of misguidance and protect them from perdition.”
Allah sent Muhammad (SAWS) to mankind after a long period of sheer ignorance: the weak were bullied and exploited, wars were the norm, and blindness of heart and insight was dominant. He was the light that guided and the heart that gathered people around him. For all this Allah (SWT)  asked the believers to love the Prophet (SAWS), respect him and follow his orders.
