On the authority of Abdullaah who said that the Messenger of Allaah -sallAllaahu alayhi wa sallam- said:
'Verily Allaah has distributed your manners between yourselves just like He distributed your provisions between yourselves.
Allaah gives the Duniya (world) to the one He loves and the one whom He doesn't love, but He doesn't give Emaan (faith) except to the one whom He loves.
