Anas reported that a Jewish boy used to serve the Prophet, may Allah bless him and grant him peace. The boy became ill and the Prophet, may Allah bless him and grant him peace, went to visit him. He sat by his head and said, "Become a Muslim." The boy looked at his father who was also sitting by his head. His father said to him, "Obey Abu'l-Qasim (may Allah bless him and grant him peace)." So the boy became a Muslim. The Prophet, may Allah bless him and grant him peace, left saying, "Praise be to Allah who has saved him from the Fire!"  

أَنَّ غُلاَمًا مِنَ الْيَهُودِ كَانَ يَخْدُمُ النَّبِيَّ ﷺ فَمَرِضَ فَأَتَاهُ النَّبِيُّ ﷺ يَعُودُهُ فَقَعَدَ عِنْدَ رَأْسِهِ فَقَالَ أَسْلِمْ فَنَظَرَ إِلَى أَبِيهِ وَهُوَ عِنْدَ رَأْسِهِ فَقَالَ لَهُ أَطِعْ أَبَا الْقَاسِمِ ﷺ فَأَسْلَمَ فَخَرَجَ النَّبِيُّ ﷺ وَهُوَ يَقُولُ الْحَمْدُ لِلَّهِ الَّذِي أَنْقَذَهُ مِنَ النَّارِ
