Dar-e-Arqam

Darul Arqam was a house that belonged to Arqam bin Arqam, who had newly accepted Islam and was situated at the outskirts of Mecca. It served as a centre where Muslims would gather, learn about their faith and worship. Owing to this recognition, it was also known by the name of Darus Salam [The Abode of Peace]. This served as the centre [for Muslims] in Mecca for three years wherein they would discreetly worship and also where the Holy Prophet (sa) held gatherings.

Later, when Hazrat Umar (ra) accepted Islam, they began openly professing their faith. According to the traditions, Hazrat Umar (ra) was the last person to accept Islam at that centre.
