BELIEVE in God and His Apostle, and spend on others out of that of which He has made you trustees: or, those of you who have attained to faith and who spend freely [in God’s cause] shall have a great reward.
Al-Hadid (Iron) Verse 7
"Allah's Apostle said, "By Him in Whose Hands my life is, none of you will have faith till he loves me more than his father and his children."
Sahih Bukhari: Volume 1, Book 2, Number 13
