Jalal was born in Tehran, into a religious family – his father was a cleric – "originally from the village of Aurazan in the Taliqan district bordering Mazandaran in northern Iran, and in due time Jalal was to travel there, exerting himself actively for the welfare of the villagers and devoting to them the first of his anthropological monographs". He was a cousin of Mahmoud Taleghani. After elementary school Al-e-Ahmad was sent to earn a living in the Tehran bazaar, but also attended Marvi Madreseh for a religious education, and without his father's permission, night classes at the Dar ul-Fonun. He went to Seminary of Najaf in 1944 but returned home very quickly. He became "acquainted with the speech and words of Ahmad Kasravi" and was unable to commit to the clerical career his father and brother had hoped he would take, describing it as "a snare in the shape of a cloak and an aba." He describes his family as a religious family in the autobiographical sketch that published after his death in 1967.
