Sunan Abi Dawud, Hadith 3089 ⓘ

Narrated Anas : A young Jew became ill. The Prophet 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 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 صلى الله عليه وسلم يَعُودُهُ فَقَعَدَ عِنْدَ رَأْسِهِ فَقَالَ لَهُ ‏"‏ أَسْلِمْ ‏"‏ ‏.‏ فَنَظَرَ إِلَى أَبِيهِ وَهُوَ عِنْدَ رَأْسِهِ فَقَالَ لَهُ أَبُوهُ أَطِعْ أَبَا الْقَاسِمِ ‏.‏ فَأَسْلَمَ فَقَامَ النَّبِيُّ صلى الله عليه وسلم وَهُوَ يَقُولُ ‏"‏ الْحَمْدُ لِلَّهِ الَّذِي أَنْقَذَهُ بِي مِنَ النَّارِ ‏"‏ ‏.‏
