Anas reported that a Jewish boy used to serve the Prophet, (ﷺ). The boy became ill and the Prophet, (ﷺ), 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 ((ﷺ))." So the boy became a Muslim. The Prophet, (ﷺ), left saying, "Praise be to Allah who has saved him from the Fire!"
حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، قَالَ: حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ ثَابِتٍ، عَنْ أَنَسٍ، أَنَّ غُلاَمًا مِنَ الْيَهُودِ كَانَ يَخْدُمُ النَّبِيَّ صلى الله عليه وسلم فَمَرِضَ، فَأَتَاهُ النَّبِيُّ صلى الله عليه وسلم يَعُودُهُ، فَقَعَدَ عِنْدَ رَأْسِهِ فَقَالَ: أَسْلِمْ، فَنَظَرَ إِلَى أَبِيهِ، وَهُوَ عِنْدَ رَأْسِهِ، فَقَالَ لَهُ: أَطِعْ أَبَا الْقَاسِمِ صلى الله عليه وسلم، فَأَسْلَمَ، فَخَرَجَ النَّبِيُّ صلى الله عليه وسلم وَهُوَ يَقُولُ: الْحَمْدُ لِلَّهِ الَّذِي أَنْقَذَهُ مِنَ النَّارِ.
