Imam al-Hadi (a.s.) lived in Yathrib, his birthplace and the country of his fathers. He spent his time in spreading knowledge and morals and in educating people the Islamic principles. He took the Prophet’s Mosque as school for that. Ulama’, jurisprudents, and narrators surrounded him taking from the springs of his knowledge that he acquired from his fathers who had illuminated the life of man with the light of knowledge and faith.
As he was a fertile source for the intellectual, scientific life in Yathrib, he was the only source that provided students with money and material means besides providing the poor and needy with what they needed. Imam al-Hadi (a.s.) did not only help or pay charity to the people of Yathrib, but his kindness included all sides of their lives. He comforted them in sorrow and in joy. He visited the sick, participated in funerals, showed kindness to the young and old, and cared for widows and orphans. He spared no good and favor unless he did to them. In return, they were very loyal to him. They surrounded him with their hearts and feelings and made him dwell in the deep of their souls.
