Hadhrat Rakb (Radiyallahu Anhu) reports that Rasulullah (Sallallahu Alayhi Wasallam) said: “Glad tidings (of Jannah) are for that person whose income is pure (halaal), his interior and exterior is good, he does not cause any harm to people. Glad tidings (of Jannah) are for that person who practices on his knowledge, spends his excess wealth (on the needy) and does not engage in useless talk.”
