[Machine] After the allegiance was pledged to Hasan ibn Ali, he seriously confronted Mu'awiya and advanced towards him, appointing Abdullah ibn Ja'far al-Tayyar at the front with ten thousand men. He then followed him with Qays ibn Sa'd leading a great army. Mu'awiya corresponded with Abdullah ibn Ja'far, promising him a million dirhams if he came to Hijaz, to which he agreed, abandoned his course, and went to Mu'awiya, who fulfilled his promise. The army dispersed, and Qays ibn Sa'd remained separate with many joining him. Those who were with Abdullah ibn Ja'far were also approached by Mu'awiya and enticed, but they did not comply until Hasan made peace with Mu'awiya, relinquishing authority to him. Hasan and his companions proceeded to meet Mu'awiya, and Hasan was treacherously wounded in the Sabat Pass by Sinan ibn al-Jarrahi al-Asadi, an ally of Banu Nasr, who stabbed him in the thigh with an abhorrent strike. Sinan held the views of the Khawarij. Hasan clutched him and fell to the ground with him. Abdullah ibn Zubyan ibn Amarah al-Tamimi leapt upon Sinan, biting his face until he severed his nose and crushed his head with a stone, killing him instantly. Thus, away with the companions of the Blaze. Hasan was carried on a stretcher to Mada'in and was hosted by Sa'd ibn Mas'ud al-Thaqafi, the uncle of al-Mukhtar, who was Ali's governor in Mada'in. He brought a doctor to treat Hasan until he recovered.
