Abdullah bin Ma'qil (may Allah have mercy on him) said: The people of al-Sawad have no covenant except (the people of) the land of al-Hirah, Ullays and Baniqya. Sharik (may Allah have mercy on him) said: The people of Baniqya had guided Jarir bin Abdullah (may Allah be pleased with him) to a ford, and the people of Ullays had hosted Abu Ubaydah (may Allah be pleased with him) and guided him to something. Yahya (may Allah have mercy on him) said: I think he means a weak point of the enemy.
