Musannaf Ibn Abi Shaybah 7371 — Those who disliked sleeping between

Al-Haytham al-Muradi said: A man asked Sayyiduna Ibn Umar (may Allah be pleased with them both) about sleeping before Isha, and he said: "One should pray and then sleep." He asked the same question three times, and he gave the same answer all three times. The third time he said to him: "One should pray and then sleep; may your eye not sleep!"
