It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that such people have testified to me—"whose words are trustworthy, among them is Sayyiduna Umar (may Allah be pleased with him), who in my view is the most trustworthy among them"—that the Prophet (peace and blessings be upon him) used to say: No voluntary prayer should be performed after the Asr prayer until sunset, and no prayer should be performed after the Fajr prayer until sunrise.

Harith bin Muawiyah Kindi says that once I set out on a journey riding an animal to ask three questions from Sayyiduna Umar (may Allah be pleased with him). When I reached Madinah Munawwarah, Sayyiduna Umar (may Allah be pleased with him) asked the reason for my coming. I said that I have come to ask about three matters. He said: What are those three matters? I said that sometimes my wife and I are in a small room, the time for prayer comes, if we both pray there, she is right next to me, and if she stands behind me, she goes out of the room. What should be done in this case? Sayyiduna Umar (may Allah be pleased with him) said: Hang a cloth between yourself and your wife, then if you wish, she can stand with you and pray. Then I asked about offering two voluntary prayers after Asr: he said that the Prophet (peace and blessings be upon him) forbade this. Then I asked him about preaching, that people demand me to deliver sermons? He said: It is up to you. From Sayyiduna Umar’s (may Allah be pleased with him) answer, it seemed that he did not consider it good to directly forbid it. I said: Should I consider your statement as final? He said: I fear that if you start storytelling or preaching, you will begin to consider yourself above them, until a time will come when, while preaching, you will consider yourself to have reached the Pleiades, as a result of which, on the Day of Resurrection, Allah will put you just as much beneath their feet.

It is narrated from Sayyiduna Umar (may Allah be pleased with him) that I heard the Messenger of Allah (peace and blessings of Allah be upon him) say: Allah forbids you from swearing oaths by the names of your forefathers. Sayyiduna Umar (may Allah be pleased with him) says: Since I heard the prohibition of this from the tongue of the Prophet (peace and blessings of Allah be upon him), I have never sworn such an oath, nor have I mentioned it in conversation or quoted it from anyone.

It is narrated from Sayyiduna Umar (may Allah be pleased with him) and Sayyiduna Hudhayfah bin Al-Yaman (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) did not collect zakat on horses and slaves.

Sayyiduna Umar (may Allah be pleased with him) once delivered a speech at "Jabiyah" during a journey and said: Once the Prophet (peace and blessings be upon him) stood to deliver a sermon just as I am standing now, and he said: I advise you to treat my companions well, and this command is also for those who come after them, and for those who come after them. After this, lying will become so widespread that a man will be ready to give testimony even before being asked for it. So whoever among you desires a place in Paradise should adhere to the "Jama'ah" (the main body), for the devil is with the lone person and is farther from two. Remember! None of you should sit in seclusion with a woman, for the third among them is the devil. And whoever feels happiness due to his good deed and sorrow due to his bad deed, he is a believer.

Sayyiduna Umar (may Allah be pleased with him) used to say that whoever wants to see the character of the Prophet (peace and blessings be upon him), he should look at the character of Amr bin Aswad.

It is narrated from Sayyiduna Umar (may Allah be pleased with him) that once we were on a journey with the Prophet (peace and blessings be upon him), a man swore an oath saying: «لَاوَأَبِي» Then another man said to him: Do not swear by the names of your forefathers. When I looked, it was the Prophet (peace and blessings be upon him).

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that when the Prophet (peace and blessings of Allah be upon him) passed away and after him Sayyiduna Abu Bakr (may Allah be pleased with him) was chosen as the Caliph, and those among the Arabs who could become disbelievers, became so, Sayyiduna Umar (may Allah be pleased with him) said to Sayyiduna Abu Bakr (may Allah be pleased with him): "How can you fight against these people when the Prophet (peace and blessings of Allah be upon him) said: 'I have been commanded to fight the people until they say La ilaha illallah (there is no god but Allah). Whoever says La ilaha illallah has protected his life and wealth from me, except for the right of Islam, and his reckoning is with Allah?' Sayyiduna Abu Bakr (may Allah be pleased with him) replied upon hearing this: 'By Allah! I will certainly fight those who differentiate between prayer and zakat, because zakat is the due right of wealth. By Allah! If they withhold even a young goat (which they used to give to the Messenger of Allah, peace and blessings of Allah be upon him), I will fight them for it.' Sayyiduna Umar (may Allah be pleased with him) says: 'Then I understood that Allah Almighty had opened the heart of Sayyiduna Abu Bakr (may Allah be pleased with him) regarding this matter, and I realized that his opinion was indeed correct.'"

It is narrated from Sayyiduna Umar (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) used to say: "No prayer should be performed after the Fajr prayer until the sun rises, and no voluntary prayer should be performed after the Asr prayer until the sun sets."

It is narrated from Sayyiduna Umar (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) decreed that the owner of the mount has the right to sit on the front seat of the mount.
