Explanation

Dar al-Arqam was located in Makkah and served as the first gathering place for early Muslims. The house belonged to a Sahabi named Arqam bin Abil Arqam (رضي الله عنه). He had several houses on his property, and he donated this one as a secret centre for propagation. It was situated at the northern base of Mount Safa, with at least one door hidden from the view of its neighbours. Arqam (رضي الله عنه) was only 12-16 years old when he embraced Islam which he kept secret. The house was an inheritance from his father. He was from Bani Makhzum, the same tribe headed by Abu Jahal.
