Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates: "I came riding on a donkey, and with me, seated behind me, was a boy from Banu Abd al-Muttalib. The Messenger of Allah (peace and blessings be upon him) was praying in an open, empty place. We dismounted, then came and joined the prayer, and we left the donkey in front of them, and he (peace and blessings be upon him) paid no attention to it. Then two little girls from Banu Abd al-Muttalib came running, one following the other, until they reached the Prophet (peace and blessings be upon him) while he (peace and blessings be upon him) was praying, and he (peace and blessings be upon him) separated them and paid no attention to it."
