Samurah bin Jundub (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Do not name your slave (child or slave) Yasar (Ease), Rabah (Profit), Najeeh (Successful), and Aflah (Prosperous), because you will say: 'Is he here?' If he is not there, then the one asking will say: 'He is not here.'" And in his narration, it is mentioned: He said, "Do not name your slave Rabah, Yasar, Aflah, and Nafi’." Narrated by Muslim.
