Sayyiduna Bara’ (may Allah be pleased with him) reports that a man from Banu Nabit (a tribe of the Ansar) came and said: I bear witness that there is no deity worthy of worship except Allah, and that you (O Prophet صلی اللہ علیہ وسلم ) are His servant and His messenger. Then he advanced and kept fighting until he was killed. The Prophet صلی اللہ علیہ وسلم said: He did little deeds but attained great reward.
