Ibn 'Umar reported Allah's Messenger (ﷺ) as saying: The night prayer consists of pairs and when you see the approach of dawn, make this number odd by one rak'ah. It was said to Ibn 'Umar (RA) : What does the (word) pair imply? He said: (It means) that salutation is uttered after every two rak'ahs.

Ibn 'Umar (Allah be pleased with both of them) reported Allah's Messenger (ﷺ) as saying: The month (of Ramadan) may consist of twenty nine days, and Shu'bah (one of the narrators) (gave a practical demonstration how the Holy prophet (ﷺ) explained to them) by unfolding his hands thrice and folding his thumb at the third turn. 'Uqba (one of the narrators in this chain of transmitters) said: I think that he said that the month consists of thirty days and unfolded his palm three times.

Ibn 'Umar (RA) reported Allah's Messenger (ﷺ) as saying: Seek it (Lailat-ul-Qadr) in the last (ten nights). If one among you shows slackness and weakness (in the earlier part of Ramadan), it should not be allowed to prevail upon him in the last week.

'Uqba bin Huraith said: I heard Ibn 'Umar saying: The Messenger of Allah (ﷺ) forbade (the preparation of Nabidh in a green pitcher (besmeared with pitch), in varnished jar, and in gourd, and he said: Prepare Nabidh in small waterskins.
