It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that once I observed for a whole month that the Prophet (peace and blessings be upon him) used to recite Surah Al-Kafiroon and Surah Al-Ikhlas in the two rak'ahs (Sunnah) before Fajr.

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that once the Prophet (peace and blessings be upon him) delayed the ‘Isha prayer so much that those who sleep had gone to sleep, those who perform Tahajjud had performed Tahajjud, and those who stay awake remained awake. Then the Prophet (peace and blessings be upon him) came out and said:“If I did not fear hardship for my Ummah, I would have delayed the ‘Isha prayer until this time.”

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) gave him a silk garment and gave Sayyiduna Usama (may Allah be pleased with him) a linen garment, and said: "The part of it that touches the ground will be in Hell."

It is narrated from Abdur Rahman A'araji that a man asked Sayyiduna Ibn Umar (may Allah be pleased with them both) about temporary marriage with women in my presence, so he replied: In the blessed era of the Prophet (peace be upon him), we did not commit any immorality or lustfulness. Then he said: I heard the Prophet (peace be upon him) say that before the Day of Judgment, the Messiah Dajjal and thirty or more great liars will certainly appear.

The previous hadith is also narrated through this second chain of transmission.

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) made this supplication at the beginning of Islam: "O Allah! Grant strength to Islam through one of these two men—Abu Jahl or Umar bin Khattab—whichever of them is more beloved to You." (Sayyiduna Umar, may Allah be pleased with him, accepted Islam.) It is thus known that Sayyiduna Umar bin Khattab (may Allah be pleased with him) was more beloved in the sight of Allah.

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: "Allah has made the truth flow upon Umar's heart and tongue." Sayyiduna Ibn Umar (may Allah be pleased with them both) says that whenever any matter was presented before the people and the people had one opinion and Sayyiduna Umar (may Allah be pleased with him) had another opinion, then the Noble Qur'an would be revealed close to the opinion of Sayyiduna Umar (may Allah be pleased with him).

Narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that he said: I have traveled with the Prophet (peace and blessings be upon him) and with Sayyiduna Umar (may Allah be pleased with him), and both of them did not pray more than two rak'ahs during travel. We were previously misguided, then Allah granted us guidance through the Prophet (peace and blessings be upon him), so now we will follow him.

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that once I observed for twenty-four or twenty-five days that the Prophet (peace and blessings be upon him) used to recite Surah Al-Kafirun and Surah Al-Ikhlas in the two rak'ahs (Sunnah) before Fajr and after Maghrib.

Salim says that regarding Hajj Tamattu’, Sayyiduna Ibn Umar (may Allah be pleased with them both) used to give the same concession which Allah has revealed in the Qur’an and which is established from the Sunnah of the Prophet (peace be upon him). Some people would say to him,“Your father used to prohibit this, why do you oppose him?”He would reply to them,“Do you not fear Allah? If Sayyiduna Umar (may Allah be pleased with him) forbade it, he also had good intentions in mind, that people should complete ‘Umrah. When Allah has made it lawful and the Prophet (peace be upon him) acted upon it, then why do you make it unlawful for yourselves? Is following the Sunnah of the Prophet (peace be upon him) better, or following Sayyiduna Umar (may Allah be pleased with him)? Sayyiduna Umar (may Allah be pleased with him) did not say to you that performing ‘Umrah in the months of Hajj is absolutely forbidden; he only said that the completion of ‘Umrah is that you travel for it separately in a month other than the months of Hajj.”
