Volume 4, Book 52, Number 152 :
Narrated by Sahl (radiallaahu `anhu)
When the helmet of the Prophet (sallallaahu `alayhi wasallam) was smashed on his head and blood covered his face and one of his front teeth got broken, ‘Ali (radiallaahu `anhu) brought the water in his shield and Fatima the Prophet’s daughter) washed him. But when she saw that the bleeding increased more by the water, she took a mat, burnt it, and placed the ashes on the wound of the Prophet and so the blood stopped oozing out.
Volume 4, Book 52, Number 153 :
Narrated by ‘Umar (radiallaahu `anhu)
The properties of Bani An-Nadir which Allah had transferred to His Apostle (sallallaahu `alayhi wasallam) as Fai Booty were not gained by the Muslims with their horses and camels. The properties therefore, belonged especially to Allah’s Apostle (sallallaahu `alayhi wasallam) who used to give his family their yearly expenditure and spend what remained thereof on arms and horses to be used in Allah’s Cause.
Volume 4, Book 52, Number 154 :
Narrated by Ali (radiallaahu `anhu)
I never saw the Prophet (sallallaahu `alayhi wasallam) saying, “Let my parents sacrifice their lives for you,” to any man after Sa’d (radiallaahu `anhu). I heard him saying (to him), “Throw (the arrows)! Let my parents sacrifice their lives for you.”
We come across many narrations in which the companions say these words to the Prophet (sallallaahu `alayhi wasallam): فِدَاكَ أَبِي وَأُمِّي (Let my father and mother be sacrificed for you!), but rarely do we see the Prophet (sallallaahu `alayhi wasallam) doing the same for his companions, for it is indeed an honor not everyone deserves. If you read about the life of Sa’d bin Abi Waqas (radiallaahu `anhu), his noble qualities, his love for Allah and His deen and the sacrifices he made, you’ll see why he was one of the very few that the Prophet (sallallaahu `alayhi wasallam) said these words to.
One might ask, are we allowed to say these words to other people, even besides the Prophet (sallallaahu `alayhi wasallam)? The answer is yes, because the Sahabah and their followers (Tabi’oon) used to say it to each other among them. So saying it to the those who deserve it, like people you love for Allah’s sake, those with knowledge and those having higher ranks is permissible.
