How Imam Reza (A.S.) Was Martyred?
It was not politically feasible for al-Mamoon to reach Baghdad accompanied by Imam al-Reza (A.S.), for that would stir the winds of dissension against him and he might not be strong enough to withstand them. 
From this standpoint, our belief that al-Mamoon was the one who plotted to end the life of the Imam (A.S.) by giving him poisoned grapes is strengthened, and the historical environment at the time helps us confirm this belief even when Ibn al-Athir, in his Tarikh, thinks that that was not possible. Prominent scholars and historians such as Shaikh al-Mufid and others have also doubted it, while others such as Sayyid ibn Tawoos, Sibt ibn al-Jawzi, and al-Arbili in Kashf al-Ghumma, have all dismissed it outright. The latter strongly defended his view, but it was nevertheless no more than a simplistic and superficial defense. Al-Mamoon’s letter to the Abbasides and the residents of Baghdad, which he wrote after the demise of Imam al-Reza (A.S.), gives such an impression. "He wrote the Abbasides and their supporters and to the people of Baghdad informing them of the death of Ali ibn
Justifications of the Treaty and its Terms of Imam Hassan Mujtaba (A.S)
Imam Hasan [a] faced all the attempts of Mu’awiyah to corner him, before the start of the war, with a lofty, sublime spirit; the spirit which knew nothing but the truth and would never lower his head before the forces of falsehood. 
The prevailing conditions at the time, however, kept him at bay, something which has rarely taken place throughout history. The army led by Imam Hasan [a] became the prey of disorder. Spies, agents and the bearers of disrupting news found their way into it. Imam Hasan [a] was on the brink of being forced to surrender to his enemy! The Ummah, which he was planning a bright and successful future for and leading its march into history, diverted its course to the advantage of his foe! That was the result of the rumours and luring promises.
All through our studies on the life of Imam Hasan [a], whether during the lifetime of his father or during his own reign, we witnessed his strength ofcharacter, his steely determination, and swift action to sort out problems and reach sound, logical solutions. This was something which was matchless. We witnessed all this and lived it, in the light of historical documents which cannot be d oubted. We witnessed it in his stirring of the zeal of the people of Kufa to defend Islam in the battle of al-Jamal.
