Abu al-Malih bin Usamah narrates: We prayed the Isha prayer in Basrah and it rained on us. Then I came (home) and asked for the door to be opened, and 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) and it rained on us, yet the sky (its rain) had not even wetted 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."
