Narrated Ibn `Umar: A man came to the Prophet while he was delivering the sermon and asked him how to offer the night prayers. The Prophet replied, 'Pray two rak`at at a time and then two and then two and so on and if you are afraid of dawn (the approach of the time of the Fajr prayer) pray one rak`a and that will be the with for all the rak`at which you have prayed." Narrated 'Ubaidullah bin `Abdullah bin `Umar: A man called the Prophet while he was in the mosque.

Narrated `Abdullah bin `Umar: Allah's Apostle offered a two-rak`at prayer at Mina. Abu Bakr, `Umar and `Uthman, (during the early years of his caliphate) followed the same practice.

Narrated Nafi`: That Ubaidullah bin `Abdullah and Salim bin `Abdullah informed him that they told Ibn `Umar when Ibn Az-Zubair was attacked by the army, saying "There is no harm for you if you did not perform Hajj this year. We are afraid that you may be prevented from reaching the Ka`ba." Ibn `Umar said "We set out with Allah's Apostle and the non-believers of Quraish prevented us from reaching the Ka`ba, and so the Prophet slaughtered his Hadi and got his head shaved." Ibn `Umar added, "I make you witnesses that I have made `Umra obligatory for me. And, Allah willing, I will go and then if the way to Ka`ba is clear, I will perform the Tawaf, but if I am prevented from going to the Ka`ba then I will do the same as the Prophet did while I was in his company." Ibn `Umar then assumed Ihram for Umra from Dhul-Hulaifa and proceeded for a while and said, "The conditions of `Umra and Hajj are similar and I make you witnesses that I have made `Umra and Hajj obligatory for myself." So, he did not finish the Ihram till the day of Nahr (slaughtering) came, and he slaughtered his Hadi. He used to say, "I will not finish the Ihram till I perform the Tawaf, one Tawaf on the day of entering Mecca (i.e. of Safa and Marwa for both `Umra and Hajj).

Narrated Nafi`: Some of the sons of `Abdullah told him (i.e. `Abdullah) if he had stayed (and not performed Hajj that year).

Narrated Nafi`: One of `Abdullah's sons said to `Abdullah (bin `Umar) "I wish you would stay this year (and not perform Hajj) as I am afraid that you will not be able to reach the Ka`ba." On that he (i.e. `Abdullah bin `Umar) said, "We went out with the Prophet (for `Umra), and when the Quraish infidel intervened between us and the Ka`ba, the Prophet slaughtered his Hadi and shaved (his head), and his companions cut short their hair." Then `Abdullah bin `Umar said, "I make you witness that I have intended to perform `Umra and if I am allowed to reach the Ka`ba, I will perform the Tawaf, and if something (i.e. obstacles) intervene between me and the Ka`ba, then I will do what Allah's Apostle did." Then after going for a while, he said, "I consider the ceremonies (of both `Umra and Hajj as one and the same, so I would like you to witness that I have intended to perform Hajj along with my `Umra." So he performed only one Tawaf and one Sai (between Safa and Marwa) and finished the Ihram of both Umra and Hajj).
