Sayyiduna Anas (may Allah be pleased with him) narrates: My maternal aunt’s son, Haritha, went on the day of the Battle of Badr to see what the situation of the battle was. He was struck by an arrow and died. My aunt, his mother, came to the service of the Prophet (peace and blessings of Allah be upon him). She said: O Messenger of Allah (peace and blessings of Allah be upon him)! If my son Haritha is in Paradise, then I will be patient and hope for reward, otherwise you will see what I do. The Prophet (peace and blessings of Allah be upon him) said: O Umm Haritha! Paradise has many levels, and Haritha is in the highest Firdaus.
