Nafi’ (may Allah have mercy on him) says: Abdullah bin Umar (may Allah be pleased with them both) had a friend in Syria who used to write letters to him. Once, Abdullah (may Allah be pleased with them both) wrote to him:“I have received information about you that you have engaged in (improper) discussion regarding the matter of destiny (Qadar). Therefore, refrain from writing letters to me, because I heard the Messenger of Allah (peace and blessings be upon him) say: ‘There will be people in my Ummah who will deny destiny (Qadar).’”

Muhammad bin Ubaid Makki, may Allah have mercy on him, says that someone said to Sayyiduna Abdullah bin Abbas, may Allah be pleased with them both: "A man has come to us who denies destiny (Qadar)." He said: "Take me to him." At that time, he had become blind. The people said: "O Ibn Abbas! What will you do to him?" He said: "By the One in Whose hand is my soul! If I gain control over him, I will bite his nose until I cut it off, and if his neck comes into my hands, I will break it. The reason is that I heard the Messenger of Allah, peace and blessings be upon him, say: 'It is as if I am seeing the women of Banu Fihr circumambulating Khazraj, their hips moving, and they are idolaters. This will be the first shirk (polytheism) of this Ummah. By the One in Whose hand is my soul! This vile opinion of theirs will lead them to the point that they will remove Allah, the Exalted, even from decreeing good, just as they have removed Him from decreeing evil.'"

Ibn Aun (may Allah have mercy on him) says: I saw Ghailan Qadari in such a state that he had been hanged at the Bab of Damascus.
