It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that when the Noble Prophet (peace and blessings be upon him) sat in Tashahhud, he would place both his hands on both his knees, raise the finger next to the thumb, supplicate, and spread his left hand over his left knee.

Upon this, the following verse was revealed: "You have no authority in this matter, whether Allah turns to them or punishes them, for they are wrongdoers."

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) led the Salat al-Khawf (prayer of fear) in such a way that he made one group stand behind him and had them perform one bowing (ruku) and two prostrations (sajdah), while the other group stood facing the enemy. Then the group that had prayed one rak’ah with the Noble Prophet (peace and blessings be upon him) left, and the other group came. The Noble Prophet (peace and blessings be upon him) had them also perform one bowing and two prostrations, and then the Noble Prophet (peace and blessings be upon him) said the salam (ended the prayer). After that, every person from both groups stood up and completed one rak’ah on their own.

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that he performed two rak'ahs of 'Isha prayer at Mina with the Noble Prophet (peace and blessings of Allah be upon him), and also performed two rak'ahs with Sayyiduna Abu Bakr (may Allah be pleased with him) and Sayyiduna Umar (may Allah be pleased with him), and during the early days of the caliphate of Sayyiduna Uthman (may Allah be pleased with him), he also performed two rak'ahs with him. Later, Sayyiduna Uthman (may Allah be pleased with him) started performing the prayer in full.

Abdur Rahman bin Umayyah asked Sayyiduna Ibn Umar (may Allah be pleased with them) that in the Noble Qur'an we find mention of the prayer of fear and the prayer in residence, but we do not find mention of the prayer during travel (even then, why is the prayer shortened during travel?) He replied: "When Allah Almighty sent the Messenger of Allah (peace and blessings be upon him), we knew nothing; we only do as we saw him doing."

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: "None of you should wrap himself in prayer like the Jews do, rather he should drape himself. The way to do this is that whoever has two garments should make one a lower garment and the other a sheet, and whoever does not have two garments but only one, should make it a lower garment and pray in it."

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that when the Muslims came to Madinah Munawwarah, there was no call to prayer (adhan) at that time, rather people would gather at an estimated time. One day they discussed this matter, and some people said that a bell should be made to inform others, as the Christians do. Some said that a horn should be made like the Jews’ horn. Sayyiduna Umar (may Allah be pleased with him) said,“Why don’t you send a man to announce the prayer?”Upon hearing this, the Noble Prophet (peace and blessings be upon him) said to Sayyiduna Bilal (may Allah be pleased with him):“Bilal, get up and announce the prayer.”
