Hadith 749
Ibn 'Umar reported: A person called (the attention) of the Messenger of Allah (ﷺ) as he was in the mosque, and said: Messenger of Allah, how should I make the rak'ahs of the night prayer an odd number? Upon this the Messenger of Allah (ﷺ) (way peace he upon him) said: He who prays (night prayer) he should observe it in pairs, but if he apprehends the rise of morning, he should observe one rak'ah; that would make the number odd (for the rak'ahs) observed by him. This was narrated by Abd Kuraib 'Ubaidullah bin 'Abdullah and Ibn 'Umar did not make mention of it.

Hadith 1199
This hadith has been narrated on the authority of Ibn 'Umar (peace be upon him) as saying: "Five (are the beasts) in killing which or their being killed in the precinct of the Ka’bah there is no sin." The rest of the hadith is the same.
Hadith 1288
Ubaidullah bin 'Abdullah bin 'Umar reported on the authority of his father (RA) that Allah's Messenger (ﷺ) combined the sunset and 'Isha' prayers at Muzdalifa and there was no prostration (i. e. any rak'ahs of Sunan or Nawafil prayers) in between them. He observed three rak'ahs of the sunset prayer and two rak'ahs of the 'Isha' prayer, and 'Abdullah (b. 'Umar) observed the prayers in this very manner (at Muzdalifa) until he met his Lord.
