Abu al-Malih narrates: I went out to the mosque on a rainy night, and when I returned I asked for the door to be opened. My father, Sayyiduna Usamah (may Allah be pleased with him), said to me: We found ourselves with the Messenger of Allah (peace and blessings be upon him) on the day of Hudaybiyah, and rain fell on us that did not even wet the soles of our sandals, when the caller of the Messenger of Allah (peace and blessings be upon him) called out: "Pray in your lodgings."
