A--- Allah the Almighty says: {No calamity befalls on the earth or in yourselves but it is inscribed in the Book of Decrees (Al-Lauh AlMahfuz) before We bring it into existence}. (Al-Hadid, 22)

'Abdullah Ibn 'Amr Ibn Al-'As (May Allah be pleased with them) reported:

"I heard Allah's Messenger (Peace be upon him) as saying: 'Allah ordained the measures (of quality) of the creation fifty thousand years before He created the heavens and the earth, as His Throne was upon water.’”(Muslim)

Jabir (May Allah be pleased with him) reported that Suraqah Ibn Malik came and said: Allah's Messenger, explain our religion to us (in away) as if we have been created just now. Whosoever deeds we do today, is it because of the fact that -the Pens have dried (after recording them) and the destinies have began to operate or these have effects in future?

Thereupon, he said: The pens have dried and destinies have begun to operate. (Suraqah Ibn Malik) said: If it is so, then what is the use of doing good deeds? Zuhair said: Then Abu Zubair said something but I could not understand that and I said: What did he say? Thereupon, he said: Act, for everyone is facilitated what he intends to do.” (Sahih Bukhari)

Narrated Abu Hurairah (May Allah be pleased with him): I said: "O Allah's Messenger! I am a young man and I am afraid that I may commit illegal sexual intercourse and I cannot afford to marry.” He kept silent, and then repeated my question once again, but he kept silent. I said the same (for the third time) and he remained silent. Then repeated my question (for the fourth time), and only then the Prophet (Peace be upon him) said: "O Abu Hurairah! The Pen has dried after writing what you are going to confront. So (it does not matter whether you) get yourself castrated or not.”(Sahih Bukhari)
