Al-Husayn ibn Sailam was a Jewish rabbi in Yathrib who was widely respected and honoured by the people of the city even by those who were not Jewish. He was known for his piety and goodness, his upright conduct and his truthfulness.

Al-Husayn lived a peaceful and gentle life but he was serious, purposeful and organized in the way he spent his time. For a fixed period each day, he would worship, teach and preach in the temple.

Then he would spend some time in his orchard, looking after date palms, pruning and pollinating. Thereafter, to increase his understanding and knowledge of his religion, he would devote himself to the study of the Torah..
