Do not call your servant Yasar (wealth), Rabah (profit), Nijih(prosperous) and Aflah (successful), for you may ask; Is he there? And someone says: No. Samurah said: These are four (names), so do not attribute more to me.
قَالَ رَسُولُ اللَّهِ ﷺ لاَ تُسَمِّيَنَّ غُلاَمَكَ يَسَارًا وَلاَ رَبَاحًا وَلاَ نَجِيحًا وَلاَ أَفْلَحَ فَإِنَّكَ تَقُولُ أَثَمَّ هُوَ فَيَقُولُ لاَ إِنَّمَا هُنَّ أَرْبَعٌ فَلاَ تَزِيدَنَّ عَلَىَّ
