Four noteworthy terms of this agreement were:
•People of Syria, Iraq, Hijaz, Yemen and other places shall enjoy amnesty against persecution,
•Friends and companions of Imam Ali (AS) and all their women and children shall be protected from all dangers,
•Mu'awiya is to immediately stop the use of abusive language with reference to Ahlul Bayt (cursing Imam Ali) after Salat of Jumu'a)
•Mu'awiya shall not appoint anyone as his successor.
Once the treaty was signed, Imam Hasan (AS) and brother Husain (AS) moved out of Kufa and settled in Medina. Over there both Imams lost no time in holding nightly meetings for Islamic discussions. The nightly meetings proved very successful and gained tremendous popularity.
More people started to attend, to hear the Imams give of their fountain of knowledge on Islam and humanity. The reputation of these meetings began to fly to far away places. People from as far away as Egypt, Iraq, Yemen, and other distant areas travelled to Medina to learn about the Islamic values. As years passed, the knowledge thus given started to bear fruits. The number of Islamic scholars multiplied and increased considerably.
In the meantime Mu'awiya, unabashedly elected to disregard the terms of his treaty with Imam Al-Hasan. a) He sent secret agents to terrorize, kidnap, or even kill innocent people specially those who were loyal to Ahlul Bayt (AS). b) Instead of helping the needy with the public treasury, Mu'awiya's governors and their surrogates used the public treasury for personal use, freely and excessively as they wished. c) Freedom suddenly died, and dictatorship took its place. d) Mu'awiya gathered a very large number of collaborators who unabashedly would do any thing for money.
