وَعَن سَمُرَةَ بْنِ جُنْدُبٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسلم: لَا تسمين غُلَاما يسارا وَلَا رباحا ولانجيحا وَلَا أَفْلَحَ فَإِنَّكَ تَقُولُ: أَثَمَّ هُوَ؟ فَلَا يَكُونُ فَيَقُولُ لَا رَوَاهُ مُسْلِمٌ. وَفِي رِوَايَةٍ لَهُ قَالَ: «لَا تسم غُلَاما رَبَاحًا وَلَا يَسَارًا وَلَا أَفْلَحَ وَلَا نَافِعًا»
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.
