Question:
Did Al-Hasan (a.) Mu’awiyah take the oath of allegiance because he was a good man?
Answer:
Ja’far As-Sadiq (a.) reported that Imam Al-Hasan (a.) said: “When the cursed Mu’awiyah learned of the murder of my father (a.), he sent the cursed illegitimate Ziyad with 150.000 fighters to Kufa and gave the order to arrest me, my brother Al-Husain, the rest of my brothers, the people of my house and my followers and loved ones and to receive from us the oath of allegiance to Mu’awiyah and to decapitate him and bring his head to Mu’awiyah, who should refuse of us.” [Ilzam-un-Nasib of Al-Ha’iri, Volume 2, page 270]
عن جعفر الصادق عليه السلام عن الإمام الحسين عليه السلام قال: وبلغ اللعين معاوية قتل أبي فأنفذ الدعي اللعين زيادا إلى الكوفة في مائة ألف وخمسين ألف مقاتل فأمر بالقبض علي وعلى أخي الحسين وسائر إخواني وأهل بيتي وشيعتنا وموالينا وأن يأخذ علينا البيعة لمعاوية فمن يأبى منا ضرب عنقه وسير إلى معاوية رأسه
Zaid Ibn Wahb reported that Imam Al-Hasan (a.) said: “By God, it is better that I sign an agreement with Mu’awiyah which averts the shedding of my blood and keeps my people safe rather than killing me and losing the people of my house and relatives. By God, if I were to fight Mu’awiyah, they would have grabbed me by the collar and handed me over to him.” [Bihar-ul-Anwar of Al-Majlisi, vol. 44 page 20 Hadith 4]
عن زيد بن وهب عن الإمام الحسن عليه السلام قال: والله لأن آخذ من معاوية عهدا أحقن به دمي وآمن به في أهلي خير من أن يقتلوني فتضيع أهل بيتي وأهلي والله لو قاتلت معاوية لأخذوا بعنقي حتى يدفعوني إليه سلما

Al-Fadl reported that Imam As-Sadiq (a.) said: “Mu’awiyah addressed himself in a letter to Al-Hasan Ibn Ali (a.): “You and Al-Husain and the companions of Ali shall come here”! Then Qais Ibn Sa’d Ibn Ubadah Al-Ansari set out with them and they came to the Levant. Mu’awiyah let them enter and prepared some speakers for them and said: “O Hasan, arise and take the oath of allegiance! He rose up and took the oath of allegiance. Then he said to Al-Husain (a.): “Rise and take the oath of allegiance! He rose and took the oath of allegiance. Then he said: “O Qais, arise and take the oath of allegiance! Qais turned to Al-Husain (a.) to see what he would order him to do, but Al-Husain (a.) said: “O Qais, he is my Imam! By which he pointed to Al-Hasan (a.).” [Ar-Rijal of Al-Kashshi, page 86 Hadith 2]
