Aishah narrated that the Messenger of Allah (s.a.w) said: " Six are cursed, being cursed by Allah and by every Prophet that came: The one who adds to Allah's Book, the one who denies Allah's Qadar, the one who rules with tyranny by which he honors whom Allah has debased, and he dishonors whom Allah has honored, and the one who legalizes what Allah forbade, and the one from my family who legalizes what Allah forbade, and the abandoner of my Sunnah."

Abdul-Wahid bin Sulaim narrated: "I arrived in Makkah and met 'Ata bin Abi Rabah. I said to him: 'O Abu Muhammad! The people of Al-Basrah speak about Al-Qadar.' He said: 'O my son! Do you recite the Quran?' I said: 'Yes.' He said: 'Then recite Az-Zukhruf to me.'" He said: 'So I recited: Ha Mim. By the manifest Book. Verily, We have made it a Qur'an in Arabic that you may be able to understand. And verily, it is in the Mother of Book with Us, indeed exalted, full of wisdom. Then he said: 'Do you know what Mother of Books is?' I said: 'Allah and His Messenger know better.' He said:'It is a book that Allah wrote before He created the Heavens, and before He created the earth. In it, it is (written): Fir'awn is among the inhabitants of the Fire, and in it is: Perish the two hands of Abu Lahab, and perish he!'Ata said: 'I met Al-Walid the son of 'Ubadah bin As-Samit the Companion of the Messenger of Allah (s.a.w) and asked him:'What was your father's admonition when he died?" He said:"He called me and said: 'O my son! Have Taqwa of Allah, and know that you will never have Taqwa of Allah until you believe in Allah, and you believe in Al-Qadar- all of it-its good and its bad. If you die upon other than this you shall enter the Fire. Indeed I heard the Messenger of Allah (s.a.w) saying: "Verily the first of what Allah created was the Pen. So He said: 'Write.' It said: 'What shall I write?' He said: 'Write Al-Qadar, what it is , and what shall be, until the end.'"
