Nuzul Al-Quran is one of the important events in the life of Prophet Muhammad (peace be upon him) more than 1,400 years ago. It was the time the first verse of the Holy Quran was revealed to Prophet Muhammad, which falls on the 17th day of the Ramadhan month. That first revelation was from Surah Al-’Alaq, from the first until the fifth verse.
The meaning of surah Al-Alaq (The clot),ayat 1-5 (from the book :The meaning of the glorious Qur'an by Mohammed Marmaduke Pickthall)
1 Read : In the name of thy Lord who createth,
2 Createth man from a clot.
3 Read : And thy Lord is the most Bounteous,
4 Who teacheth by the pen,
5 Teachet man that which he knew not.
