It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Every nation has its Magians, and the Magians of my nation are those who say that there is no destiny. If these people fall ill, do not visit them, and if they die, do not attend their funerals."

(Second chain) The Noble Prophet (peace be upon him) said: "Indeed, in every nation there are Magians, and the Magians of my nation are those who deny destiny. So if these people die, do not attend their funerals, and if they fall ill, do not visit them."

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Soon there will be metamorphosis in my Ummah (i.e., their forms will be distorted). Beware! This will be among those who deny destiny and among the heretics."

It is narrated from Sayyiduna Hudhayfah bin Yaman (may Allah be pleased with him), the Messenger of Allah (peace and blessings be upon him) said: "Indeed, in every nation there are Magians, and the Magians of this Ummah are those who say that there is no destiny. If any of them falls ill, do not visit him, and if any of them dies, do not attend his funeral. These people will be the followers of Dajjal, and it is incumbent upon Allah to join them with him."

It is narrated from Sayyiduna Abu Darda’ (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said:“The disobedient and ill-mannered, the one who constantly drinks alcohol, and the one who denies destiny will not enter Paradise.”

It is narrated from Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) came out one day and the people were discussing the topic of destiny (qadar). The Prophet (peace and blessings be upon him) became so angry that it seemed as if a pomegranate seed had burst on his face (i.e., his face turned red with anger). Then the Prophet (peace and blessings be upon him) said: "What is wrong with you? You are striking one part of Allah’s Book against another. It was for this very reason that the people before you were destroyed." Sayyiduna Abdullah said: Never did I feel so much envy for missing a gathering in which the Messenger of Allah (peace and blessings be upon him) was present as I did for this gathering, wishing that I had not been present (so that I would not have become the subject of the Prophet’s anger).

Sayyiduna Umar (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Neither join the gatherings of the Qadariyyah (those who deny predestination), nor appoint them as rulers (or do not argue and debate with them)."

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.
