Mamoon at that time was drunk.
Mamoon at that time was drunk. He armed himself with a sword and accompanied by his servants He broke into the Imam's bedroom and attacked the sleeping Imam leaving the bedroom only after he was sure that he had cut the Imam into pieces. Next day, when he was informed of what he had done on (he previous night, Mamoon was sorry for his actions and sent his special servant Yasir to the Imam's house to inquire about the Imam's condition.
To his bewilderment, Yasir saw the imam (A.S) safe and sound, brushing his teeth! Yasir went back informed Mamoon that the Imam was well. Mamoon a bag containing 20,000 dinars to the Imam with Yasir. Yasir then requested the Imam (A.S) to give him the shirt that he was wearing! The Imam (A.S) removed his shirt for Yasir who saw that there was not even a single scratch on the Imam's body.
Smilingly, the Imam (A.S.) asked Yasir if this was Mamoon's idea and was linked with the previous night's event. Yasir replied that he was now acting on his own and that Mamoon was truly sorry for what he had done the previous night. In the meantime, Mamoon, too, came to Imam (A.S.) to apologise for his misbehaviour He gave the Imam (A.S) as a gift the sword that he had used against the Imam (A.S.) and the horse on which he rode to go to the Imam's house to kill him.
On the other hand the Imam (A.S.) made Mamoon promise never to use liquor again. Mamoon then warned his daughter never to complain to him about the Imam (A.S.) or else he would never see or talk with her. A year after his marriage to Ummul Fazl, Imam (A.S.) returned to Medina. Ummul-Fazle came with him but kept on writing letters to her father complaining that the Imam (.A.S.) had married another woman. Mamoon's reply was, "I did not give you in marriage to Abu Jaffer so that !
should make for him Haram (Forbidden) what Allah has made Halal (Legitimate)." In Medina, Imam's main job was to serve Islam, One of" his greatest achievements was to weaken the Waqifia Movement which had been formed on the death of Imam Musa Kazim (A.S ) and which had been a cause of serious trouble to Imam Reza (A.S.). Because of Imam Taqi's efforts Waqifia Movement was no more a threat to Islam.
Scholars from all over the world would come to learn from in various branches of knowledge such as philosophy, literature and jurisprudence and then go back to their countries to benefit others with what they had learnt from the Imam (A.S,).
