A young Jewish boy used to serve the Prophet ﷺ and he became sick. So the Prophet ﷺ went to visit him. He sat near his head and asked him to embrace Islam. The boy looked at his father, who was sitting there; the latter told him to obey Abul-Qasim and the boy embraced Islam. The Prophet ﷺ came out saying: "Praises be to Allah Who saved the boy from the Hell-fire." (Using translation from Bukhārī 1356)
أَنَّ غُلَامًا مِنَ الْيَهُودِ كَانَ يَخْدُمُ النَّبِيَّ ﷺ فَمَرِضَ فَأَتَاهُ النَّبِيُّ ﷺ يَعُودُهُ فَقَعَدَ رَسُولُ اللهِ ﷺ عِنْدَ رَأْسِهِ فَنَظَرَ الْغُلَامُ إِلَى أَبِيهِ فَقَالَ أَطِعْ أَبَا الْقَاسِمِ فَأَسْلَمَ فَخَرَجَ رَسُولُ اللهِ ﷺ وَهُوَ يَقُولُ الْحَمْدُ لِلَّهِ الَّذِي أَنْقَذَهُ بِي مِنَ النَّارِ
