Abdur Rahman bin Ayman (may Allah have mercy on him) once asked Sayyiduna Ibn Umar (may Allah be pleased with them both) about the issue of divorce during menstruation. Abu Az-Zubair was listening to this conversation. Sayyiduna Ibn Umar (may Allah be pleased with them both) said that he had divorced his wife during her menstruation. Sayyiduna Umar (may Allah be pleased with him) went and informed the Prophet (peace and blessings be upon him) about this. The Prophet (peace and blessings be upon him) said: "Tell him to take her back, then if he wants to divorce her, he should do so during her period of purity." And the Prophet (peace and blessings be upon him) also recited this verse from Surah Al-Ahzab in this manner: "O Prophet (peace and blessings be upon him), when you people divorce your wives, then divorce them at the beginning of their waiting period" (meaning, divorce should be given during the period of purity, not during menstruation).

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that he divorced his wife while she was in her "periods," and he also informed Sayyiduna Umar (may Allah be pleased with him) about this. Sayyiduna Umar (may Allah be pleased with him) presented himself in the court of the Messenger of Allah (peace and blessings be upon him) and informed the Prophet (peace and blessings be upon him) about it. The Prophet (peace and blessings be upon him) said: He should keep her with him until she becomes pure from those days, then her next period comes and she becomes pure from that as well. Then, if he decides to divorce her, he may divorce her according to the command of Allah, and if he decides to keep her, he may keep her.

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: "No person should eat from the meat of his sacrificial animal for more than three days." Because of this, Sayyiduna Ibn Umar (may Allah be pleased with them both) would not eat the meat of the sacrificial animal after sunset on the third day. (Later, this ruling was abrogated.)

This same narration from Salim (may Allah have mercy on him) is reported regarding the sacrificial and Hadi animals.

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "If a pilgrim in the state of Ihram does not find shoes, he should wear leather socks, but he should cut them below the ankles."

Sayyiduna Ibn Umar (may Allah be pleased with them both) used to offer voluntary prayers on his mount, regardless of which direction it was facing, and he used to say that he had seen the Prophet (peace and blessings of Allah be upon him) doing the same.

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that a Bedouin man called out and asked the Prophet (peace and blessings be upon him) about the lizard: "What is your opinion regarding it?" The Prophet (peace and blessings be upon him) replied: "I neither eat it nor do I declare it unlawful."

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) used to take allegiance on the condition of listening and obeying, then he would say: "As much as you are able (you will listen and obey as far as possible)."

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) appointed Dhu’l-Hulaifah as the miqat for the people of Madinah, Juhfah for the people of Sham, and Qarn for the people of Najd, and people say that the Prophet (peace and blessings be upon him) appointed Yalamlam as the miqat for the people of Yemen.

Jabalah says that Sayyiduna Abdullah bin Zubair (may Allah be pleased with him) used to give us dates to eat. In those days, people were facing extreme hardships. One day, we were eating dates when Sayyiduna Ibn Umar (may Allah be pleased with them both) passed by us and said, "Do not eat several dates at once, because the Prophet (peace and blessings be upon him) forbade eating several dates at once without your brother’s permission." Imam Shu’bah (may Allah have mercy on him) says, "In my opinion, the statement about permission is the speech of Sayyiduna Ibn Umar (may Allah be pleased with them both)."
