Abu Huraira reported (Radiyallahu `anhu) that a person came to Messenger of Allah (Sallallaahu `alayhi wa sallam)and asked,
“who among people is most deserving of my fine treatment?”
He (Peace be Upon Him) said,
“Your mother, then your mother, then your mother, then your father, then your nearest, then nearest”

Umm `Atiyyah (Radiyallaahu `anha) narrated that the Prophet (Sallallaahu `alayhi wa sallam) commanded,
“Let the free women, the virgins, and the menstruating women go out to attend the ‘Eed prayer, and witness the goodness and the supplications of the believers. As for the mentruating women, they should stay away from [praying on] the musallaa.”
