The Prophet Muhammad was the last prophet charged with warning humanity like all the other Messengers the Prophet called people to the true path, to have faith in God, to live for the hereafter and to exercise good morality. In his time, some people have elected to follow the most mistaken paths in order to supposedly find salvation. These paths were full of perversion, superstition and nonsense.
Our Prophet aroused them from their ignorance and heedlessness calling them to the path of God. He made great efforts for their salvation in their lives of this world and of the hereafter. When he communicated the message of the Quran our Prophet was exposed to enormous oppression and animosity. Yet he took no notice of these. Our Prophet upon whom great compassion was bestowed drew his power from the love of God and knew that our Lord was always with him.
God commands the prophet thus in one verse. Proclaim what you have been ordered to and turn away from the idolaters. We are enough for you against the mockers. (Surat al-Hijr:94-95)
The prophet Muhammad first told people of God's might and of the proofs of His incomparable creation. He then explained them that God had no equal and was the sole Lord of all.
Say: ''What do you think? If God made it permanent night for you till the Day of Resurrection, what deity is there other than God to bring you light? Don't you then hear?'' Say: ''What do you think? If God made it... permanent day for you till the Day of Resurrection, what deity is there other than God to bring you night to rest in? Don't you then see?'' (Surat al-Qasas:71-72)
