In the year 595, he took part in trading with Khadija and within a short span of time, she earned lots of profit in her business, she got the identity of a true heart like Mohammad(SM). She was a wealthy lady at that time and by way of achieving the identity of a great personality like Mohammad (SM), she proposed to him for marriage. He told her that he would marry her under one condition- she had to bestow her wealth and fortune for the sake of Islam on the promise to live like the poor, the way he himself lives . Khadeja, having heard such proposal agreed to such condition and they got married. At that time, his age was 25, and she was 40.
After their marriage, an epidemic was taken place in the country that time. Mohammad(SM) had distributed all the resources he had possessed from Khadeja in order to remove the adversity of the people. At that time, the thought of sacrifice for the good of the people were intensified and he was influenced for devotion towards almighty Allah day by day. Apart from Mecca three miles away, in the cave of Hera, he was absorbed in deep meditation of almighty Allah. Such process of supplication continued for forty years. One day, during his meditation, the angel Jibrail (AM) came unto him and said," Oh! Mohammad, you are the rusul of Allah, you have been sent by Allah". And thereafter, a message of Allah came, "Read in the name of your lord, from this day onward, in the cave of Here, Mohammad (SM) used to receive messages from Allah through massager, Jibrail (AM), he got accurately and complete message of the holy Quran, with his unquestionable, the ultimate and the complete code of life. In order to convey the message of peace and solidarity, he had struggled through out his life. The non-Muslim troubled in many ways, they threw stones at him, spat at him, beat him and cursed him. He was tormented in various ways, he would tolerate all the misdeeds of the people, his sole message was," Those people who have unknowingly behaved with me in such a manner, I pray for them to Allah for salvation and forgiveness. The holy Quran has come down to this world with full codes, ethics and directions of Allah. Muhammad (SM) had achieved such messages from Allah directly and it is a recognizing phenomenon that the holy Quaran is completely bedded on super human creation.
