Prophethood

Muhammad (PBUH) was born amidst a polytheistic (unbeliever) society. He was saddened and sick of the corrupt society around him. He often went to Hira cave in the mountain near Makkah, later known as Jabal An-nur (the mountain of Light) where he meditated and pondered over the prevailing darkness brought about by ignorance. There he often remained deep in thought in communion with the unseen yet All-Pervading God of the Universe. One night, while he was meditating in the Hira cave, the Angel Gabriel (peace be upon him) came to him. The Angel aroused him and his mighty voice reverberated in his ears. He was perplexed and did not know what to do. He was asked to read. He replied: "I cannot read!" The Angel repeated three times asking Muhammad (PBUH) to read, but he replied the same answer. Finally the Angel asked:
[Read in the name of your Lord , who created man from a clot. Read in the name of your God, the Most Bountiful, who taught by means of the pen, and taught man what he did not know.] (Qur'an 96: 1-5)
This was the first revelation received by Muhammad (PBUH). He was 40 years old at that time. The revelation continued to come to him from time to time in a period of 23 years. These series of revelation were arranged according to the divine guidance given to Prophet Muhammad (PBUH), and later collected in the form of a Mushaf (book) the Qur'an (Reading). Most of its verses have clear meaning. Some verses are interpreted in conjunction with other verses and some others were interpreted by the Prophet (PBUH) himself through his words, actions and agreements which are known as his Sunnah (Traditions). The Qur'an and the Sunnah together constitute the guidance and way of life for those who submit their life to Allah (God) (SWT). People who follow this guidance and way of life are guaranteed by Allah (SWT) to be saved in this world and the Hereafter.
