Musannaf Ibn Abi Shaybah 18531 — A man asking permission to enter

Mujahid (may Allah have mercy on him) said: Ata (may Allah have mercy on him) and some sisters of his lived in one house in Makkah. Among the people of Makkah, a man would go in and out to his family many times in a night, and Ata used to come to them at night. He asked Sayyiduna Ibn Abbas (may Allah be pleased with them both): "Should I seek their permission every time I go in to them?" Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: "Yes," and he did not allow him to go in to them without permission.
