Assalamu alaikum wa rahmatullahi wa barakatuhu!
In the Name of Allah, Most Gracious, Most Merciful
His religion is Islam, the only religion that leads to success and safety. Allah said:
And whoever seeks a religion other than Islam, it will never be accepted of him, and in the Hereafter he will be one of the losers.
(Surah Aale Imraan, Verse 85)
It is the religion that came to free human beings from the shackles of misguidance; it is an easy religion, and it is a comprehensive, complete and perfect religion.
..This day, I have perfected your religion for you, completed My Favour upon you, and have chosen for you Islam as your religion ..
(Surah Maaidah, Verse 3)
Islam came to free people from servitude to those who themselves are slaves, and to guide them to worship the Lord of all slaves. It came to take them from the narrowness of this world to the vastness of the Hereafter; from the darkness of polytheism to the light of Islamic monotheism; from the misery of disbelief to the happiness of Faith.
It is a religion that is at once appropriate and valid for all times and all places. The One Who legislated Islam as a religion is alone able to forgive sins, and He alone knows both what His slaves outwardly display and what is hidden in the deepest recesses of their hearts.
This perfect and well balanced religion came with beneficial knowledge and good deeds, which is what makes its adherents distinct from Jews and Christians. The Jews had knowledge, but it did not benefit them since they did not apply it. The Christians, on the other hand, strove to perform good deeds, but since they lacked knowledge, they strayed from the Straight Path. Islam is the Straight Path, the path that is followed by those who have not incurred upon themselves Allah's wrath, and who are not misguided.
Despite being illiterate, the Prophet Muhammad (saw) was sent to recite to people Allah's verses, to purify them, and to teach them the Book and wisdom; for, prior to his advent, they had been in manifest error.
Islam came to forbid lying and the giving of false testimony; it came to forbid oppression and tyranny; it came to forbid cheating people in the buying and selling of goods. Islam came to forbid all forms of wrongdoing.
And it also came to preserve the sanctity and dignity of human life - to protect the heart with faith; to protect the well being of the human body, by legislating laws that achieve that effect; to protect people's wealth from being wrongly seized or taken; to protect people's honour from all forms of slander and backbiting; to safeguard people's lives, by forbidding the wrongful shedding of blood; and to protect the mind from anything that diminishes or outright destroys its ability to function properly.
