It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that at the encampment of the Prophet (peace and blessings be upon him)—which was in the valley of Dhul-Hulaifah—a (certain) angel came and said: "You are in the blessed Batha." Musa bin Uqbah (may Allah have mercy on him) says that Salim was also with us, and he made his she-camel sit at the very place where Sayyiduna Ibn Umar (may Allah be pleased with them both) used to make his she-camel sit, and he would carefully search for the Prophet’s (peace and blessings be upon him) encampment, which was lower than the mosque in the valley, and exactly between the mosque and the road.
