Lam

The Banu Lam were a Tayy tribal confederation in Najd, named after Lam ibn Harita. In 1337 their clans were among the tribes of the western Najd steppe between Medina and al-Yamama.

The Al Kathir, one of the tribe's main branches, seized a large caravan from Basra at al-Lusafa in 1377. Around 1457 they joined the Anazzah against the Dhafeer at al-Sirr, where the camps faced each other for twenty days. In 1613 the Fudhool fought the Mutayr at al-Arma. Lam clans also settled around Unaizah in Qasim, while others moved into southern Iraq.
