He was from the family of Muhammad ibn Abu Bakr as Siddiq, al-Baghdadl al-Hanbali.
He was born in 509 or 510 A.H. Upon reaching adolescence, his aunt took him to Ibn Nasir from whom he learned a great deal. He came to love preaching while barely having reached the age of puberty, and from then started to give sermons to the people.
While still very young he became known as a religious person who would not socialise with anyone and would not eat from any food whose source was doubtful. He would only leave his house for prayer and he would not play with others similar to his age. He was a person of very great determination, ambition and he spent all his life busy in seeking knowledge, preaching and authoring.
