Narrated by Urwa bin Az-Zubair
Hakim bin Hizam (radiallaahu `anhu) said, “I asked Allah’s Apostle for something, and he gave me. I asked him again, and he gave me, and said to me. ‘O Hakim! This wealth is like green sweet (i.e. fruit), and if one takes it without greed, then one is blessed in it, and if one takes it with greediness, then one is not blessed in it, and will be like the one who eats without satisfaction. And an upper (i.e. giving) hand is better than a lower (i.e. taking) hand,’ I said, ‘O Allah’s Apostle! By Him Who has sent you with the Truth. I will not ask anyone for anything after you till I leave this world.” So, when Abu Bakr (radiallaahu `anhu) during his Caliphate, called Hakim to give him (some money), Hakim (radiallaahu `anhu) refused to accept anything from him. Once ‘Umar (radiallaahu `anhu) called him (during his Caliphate) in order to give him something, but Hakim refused to accept it, whereupon ‘Umar (radiallaahu `anhu) said, “O Muslims! I give him (i.e. Hakim) his right which Allah has assigned to him) from this Fai ‘(booty), but he refuses to take it.” So Hakim (radiallaahu `anhu) never took anything from anybody after the Prophet (sallallaahu `alayhi wasallam) till he died.

Narrated by Nafi
‘Umar bin Al-Khattab (radiallaahu `anhu) said, “O Allah’s Apostle! I vowed to observe Itikaf for one day during the Pre-lslamic period.” The Prophet (sallallaahu `alayhi wasallam) ordered him to fulfill his vow. ‘Umar (radiallaahu `anhu) gained two lady captives from the war prisoners of Hunain and he left them in some of the houses at Mecca. When Allah’s Apostle (sallallaahu `alayhi wasallam) freed the captives of Hunain without ransom, they came out walking in the streets. ‘Umar (radiallaahu `anhu) said (to his son), “O Abdullah! See what is the matter.” ‘Abdullah (radiallaahu `anhu) replied, “Allah’s Apostle has freed the captives without ransom.” He said (to him), “Go and set free those two slave girls.”
(Nafi added:) Allah’s Apostle (sallallaahu `alayhi wasallam) did not perform the ‘Umra from Al-Jarana, and if he had performed the ‘Umra, it would not have been hidden from ‘Abdullah.
