The Pause (fatra)

After the first message thus received, revelation ceased for a certain period (called fatra) and then resumed:

Narrated Jabir bin 'Abdullah Al-Ansari while talking about the period of pause in revelation reporting the speech of the Prophet, 'While I was walking, all of a sudden I heard a voice from the heaven. I looked up and saw the same angel who had visited me at the Cave of Hira' sitting on a chair between the sky and the earth. I got afraid of him and came back home and said "Wrap me (in blankets)" and then Allah revealed the following holy verses (of the Qur'an): O you covered in your cloak, arise and warn (the people against Allah's punishment) ... up to "and all pollution shun".'

After this revelation came strongly and regularly. [Bukhari, I, end of No. 3.]
