Narrated Anas :
A young Jew became ill. The Prophet ﷺ went to visit him. He sat down by his head and said to him: Accept Islam. He looked at his father who was beside him near his head, and he said: Obey Abu al-Qasim. So he accepted Islam, and the Prophet ﷺ stood up saying: Praise be to Allah Who has saved him through me from Hell.

حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، حَدَّثَنَا حَمَّادٌ، - يَعْنِي ابْنَ زَيْدٍ - عَنْ ثَابِتٍ، عَنْ أَنَسٍ، أَنَّ غُلاَمًا، مِنَ الْيَهُودِ كَانَ مَرِضَ فَأَتَاهُ النَّبِيُّ ﷺ يَعُودُهُ فَقَعَدَ عِنْدَ رَأْسِهِ فَقَالَ لَهُ " أَسْلِمْ " . فَنَظَرَ إِلَى أَبِيهِ وَهُوَ عِنْدَ رَأْسِهِ فَقَالَ لَهُ أَبُوهُ أَطِعْ أَبَا الْقَاسِمِ . فَأَسْلَمَ فَقَامَ النَّبِيُّ ﷺ وَهُوَ يَقُولُ " الْحَمْدُ لِلَّهِ الَّذِي أَنْقَذَهُ بِي مِنَ النَّارِ " .
