Abū Muḥammad (al-Ḥasan al-‘Askarī), peace be on him, was detained by ‘Alī b. Awtāmish. The latter was violent in his hostility to the family of Muḥammad, peace be on them, and severe on the family of Abū Ṭālib. He was told to treat him (badly) and he did so.
Yet (al-Ḥasan al-‘Askarī) was only with him for a day and he began to treat him with humility. He did not raise his eyes to him out of respect and honour. He would come from him and he had become the most perceptive of men in respect to him and the best of them in his words about him.
