Abu ‘Abdillah al-Harith ibn Asad al-Muhasibi, may Allah have mercy on him, was born in Basra. He then settled down in Bagdad and passed away there. He was a great imam, an ‘arif, and a person who spoke with great wisdom. He was unparalleled in his era as regards his piety, knowledge, social dealings and circumstances.
His exact date of birth is not known, but he was born around 165 A.H. He passed away in Baghdad in 243 A.H.
He was an ardent worshipper, a Sufi, an ascetic, a jurist, a legist, a theologian, an admonisher who could cause people to cry, and a scholar and narrator of Hadith. He was blessed with eloquent language and masterly expression. If he spoke to you about a matter in order to encourage you to do it and warn you against doing it, he will portray is as though you were seeing it with your very own eyes and that you were directly perceiving it. He will not stop talking with you until he will satisfy you with proofs and evidence, and fills you with conviction with what he is saying. And he did not say anything but good words of advice.
