It is narrated from Sa’ib bin Yazid (may Allah have mercy on him) that Sayyiduna Umar (may Allah be pleased with him) said: Sometimes some people of the Quraysh would sit at the door of Sayyiduna Ibn Mas’ud (may Allah be pleased with him) (in order to learn something). When the shadow would decline, he would say: Get up, now the remaining time is for Satan. Then, whoever he passed by, he would make them get up strictly. In this way, he was making people get up when he was told: This is the slave of Banu Hassas who recites poetry. He called him and asked: What poetry have you recited? He said:

If you have decided to travel early in the morning, then leave Salimi, for old age and the religion of Islam are sufficient to prevent a person from evil.

He (Umar) said: That is enough, you have spoken the truth, you have spoken the truth.

It is narrated from Sa’ib bin Yazid (may Allah have mercy on him), he said that when Sayyiduna Umar (may Allah be pleased with him) would pass by us / near us at noon, he would say: Get up, take a nap (qailulah), the remaining time is for the devil.

It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that he used to take a midday nap after offering the Friday prayer.

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that when the prohibition of alcohol was revealed, the favorite drink of the people of Madinah was made from dried and fresh dates. Once, I was serving alcohol to the companions of the Messenger of Allah (peace and blessings be upon him) at the house of Sayyiduna Abu Talhah (may Allah be pleased with him), when a man passed by and said: "Alcohol has been made unlawful." They did not even ask when it was made unlawful or say that they would investigate; rather, they said: "O Anas! Dispose of this alcohol." Then they took a midday nap at the house of Sayyidah Umm Sulaym (may Allah be pleased with her) until the intensity of the sun decreased, and they performed ghusl (ritual bath). Then Sayyidah Umm Sulaym (may Allah be pleased with her) applied perfume to them, and then they went to the service of the Prophet (peace and blessings be upon him), and the matter was exactly as that man had said. Sayyiduna Anas (may Allah be pleased with him) says: After that, they never even touched alcohol to their lips.
