Ali, Mu`awiya and Amr ibn al-Aas.
Ali, Mu`awiya and Amr ibn al-Aas. One of the Kharijites named Bark son of Abdullah undertook to kill Mu`awiya; another named Amr bin Bakr promised to do away with Amr ibn al-Aas; and a third named Abdur Rahman ibn Muljam took the responsibility of assassinating Ali. The above-mentioned three Kharijites decided to kill Ali, Mu`awiya, and Amr ibn al-Aas, during one and the same night.
These three persons were very fanatical, revengeful and daring and were prepared to achieve their object at any cost. However, in the case of Abdur Rahman ibn Muljam a strange thing happened which spurred his resolve and made it so firm that even if the other two Kharijites had hesitated in killing Mu`awiya and Amr ibn al-Aas; there was no likelihood of his wavering in the assassination of Ali. It so happened that he came from Mecca to Kufa and stayed there with a friend of his.
There he suddenly met a woman named Qattam daughter of Al-Akhzar who was a matchless beauty of her time, and whose father and brother were killed in the Battle of Nahrawan. Abdur Rahman fell in love with her and proposed to her at once. She asked him as to what dowry he would give her. He told her that he would give her anything she desired. Thereupon she said: “I want you to give me three thousand dirhams, one slave and one slave-girl and also to assassinate Ali son of Abu Talib”.
He replied: “It is easy to provide three thousand dirhams, a slave and a slave- girl, but how can I assassinate Ali?” She replied: “Kill him with some trick. If you kill him you will feel satisfied and will also enjoy my company for a long time”.
Before having met Qattam and conversed with her Abdur Rahman ibn Muljam was somewhat shaken in his resolution to assassinate Ali, because in spite of all his meanness it was not an easy task for him to kill the Imam for an offence with which he had no concern. Similarly it was also not easy for him to take a dreadful step, whose result was likely to be extremely dangerous.
However, fate willed it that Abdur Rahman ibn Muljam should become confirmed in his resolve and get ready to commit the most heinous crime. Fate took out a new arrow from its quiver and gave it in the hand of ibn Muljam to aim it at the Imam's bosom. Fate took Abdur Rahman ibn Muljam to his friend's house and also brought Qattam at that place.
