The lesson
- He was called Zayn al-Abidin for his worship: Malik ibn Anas reports that he prayed a thousand rak'as a day (al-'Ibar of al-Dhahabi), and al-Zuhri narrated that the Prophet said a caller on the Day of Resurrection will ask, 'Where is Zayn al-Abidin?', and it is as if I see my son Ali ibn al-Husayn ('Ilal al-Shara'i' of al-Saduq). He was called Dhu l-Thafanat for the calluses that prostration left on his forehead, palms and knees (Wafayat al-A'yan; Muruj al-Dhahab).
- When he rose to pray he trembled; asked why, he said: Do you know before whom I am going to stand? (Siyar A'lam al-Nubala of al-Dhahabi; al-'Iqd al-Farid). Malik ibn Anas reports that when he put on ihram and said the talbiya he fainted and fell from his mount (Siyar A'lam al-Nubala).
- Clear hadiths in the Shia sources name him his father's successor (al-Kafi), and the hadiths of the Prophet naming the Imams include his name (al-Ikhtisas; I'lam al-Wara). Al-Shaykh al-Mufid gives his superiority in knowledge and practice as proof (al-Irshad). The Prophet's sword and armour, kept by the rightful Imam, were with him, as even Ibn Sa'd records (al-Irshad; al-Tabaqat al-Kubra).
