Messenger of Allah ﷺ forbade us to give names to our servants as these four names: Aflah (Successful), Rabdh (Profit), Yasar (Wealth), and Nafi' (Beneficial). (Using translation from Muslim 2136a)
نَهَانَا رَسُولُ اللهِ ﷺ أَنْ نُسَمِّيَ رَقِيقَنَا بِأَرْبَعَةِ أَسْمَاءٍ نَافِعٍ وَأَفْلَحَ وَرَبَاحٍ وَيَسَارٍ
