'Abdullah bin '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; so when you see the new moon observe fast and when you see (the new moon again at the commencement of the month of Shawwal) then break It, and if the sky is cloudy for you, then calculate it (and complete thirty days).
'Abdullah bin 'Umar (RA) reported that he reached the Ka’bah and Allah's Apostle (ﷺ) had entered therein, and Bilal (RA) and Usama too. 'Uthman bin Talha closed the door for them, and they stayed there for a considerable time, and then the door was opened and Allah's Apostle (ﷺ) came out, and I went upstairs and entered the House and said: Where did Allah's Apostle (ﷺ) observe prayer? They said: At this very place. I, however, forgot to ask them about the (number of) rak'ahs that he observed.
Abu Hurairah (RA) reported Allah's Messenger (ﷺ) as saying: A Muslim who emancipates a Muslim (slave), Allah will save from Fire every limb of his for every limb (of the slave). Sa'id bin Marjana said: When I heard this hadith from Abu Hurairah (RA) , I went away and made a mention of it to 'Ali bin Husain and he at once emancipated the slave for which Ibn ja'far was prepared to pay ten thousand dirhams or one thousand dinars.
Abdullah (b. Umar) (RA) reported: Allah's Messenger (ﷺ) ordered the killing of dogs and we would send (men) in Madinah and its corners and we did not spare any dog that we did not kill, so much so that we killed the dog that accompanied the wet she-camel belonging to the people of the desert.
