Ali bin Abdur Rahman Mu'awi (may Allah have mercy on him) says that once I had the opportunity to pray next to Sayyiduna Ibn Umar (may Allah be pleased with them both). I began to turn over pebbles, so he forbade me from doing so and said that this is a satanic act. However, it is permissible to do it in the manner I saw the Prophet Muhammad (peace and blessings be upon him) do: he would move them like this. The narrator demonstrated by passing his hand (he would level the place of prostration, but would not keep doing it repeatedly and spoil the prayer).

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: "Do not take the Noble Qur'an with you when you go on a journey; I fear that it may fall into the hands of the enemy."

Imam, may Allah have mercy on him, says that I heard Sufyan saying that he had made a vow to perform i'tikaf in Masjid al-Haram. He asked the Prophet Muhammad (peace be upon him) about it, so the Prophet (peace be upon him) ordered him to fulfill that vow. Someone asked Sufyan, "This narration has been transmitted by Ayyub from Nafi' on the authority of Sayyiduna Ibn Umar (may Allah be pleased with them both), that Sayyiduna Umar (may Allah be pleased with him) had made this vow?" He replied, "Yes!"

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: "It is the right of every Muslim that three nights should not pass in such a way that his will is not written and kept with him."

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that once the Noble Prophet (peace and blessings be upon him) dispatched a detachment towards Najd. Their share became twelve camels each, and the Noble Prophet (peace and blessings be upon him) also gave us one camel each as a reward.

Nafi' reports that once in the valley of Dajnan, Sayyiduna Ibn Umar (may Allah be pleased with them both) had the call for prayer announced, then made this proclamation: "Pray in your tents." And he narrated this hadith from the Prophet Muhammad (peace and blessings be upon him) that the Prophet (peace and blessings be upon him), while traveling on cold nights or rainy nights, would have the call for prayer announced and then proclaim: "Pray in your tents."

It is narrated, most likely as a marfu’ hadith, from Sayyiduna Ibn Umar (may Allah be pleased with them both) that whoever says“In sha Allah”while taking an oath, then he has the choice: if he wishes to fulfill his oath, he may do so, and if he wishes to retract from it, he may do so without becoming a perjurer.

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) forbade selling the unborn offspring of a pregnant animal that is still in its mother's womb.

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that on the day of the conquest of Makkah, the Prophet Muhammad (peace and blessings be upon him) was saying on the steps of the Ka'bah: "All praise is due to Allah who fulfilled His promise, helped His servant, and defeated all the armies single-handedly. Be aware! The blood money (diyah) for one killed by a stick or staff is one hundred camels. According to some chains of narration, this is a severe diyah, which includes forty pregnant she-camels. Be aware! Every pride, every blood, and every claim of the time of ignorance is under my two feet. However, the office of providing water to the pilgrims and the custodianship of the key of the Sacred House (Ka'bah), I maintain these offices for their current holders as long as the world remains (these offices will remain with these people)."

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: "The people of Madinah should assume ihram from Dhu'l-Hulayfah, the people of Sham from Juhfah, the people of Yemen from Yalamlam, and the people of Najd from Qarn." People asked Sayyiduna Ibn Umar (may Allah be pleased with them both), "Where is the miqat for the people of Iraq?" He replied, "At that time, there was no miqat for it."
