Anas رضى الله عنه reported: A young Jewish boy used to serve the Prophet and he became sick, so the Prophet went to visit him. He sat near his head and asked him to embrace Islam. The boy looked at his father, who was sitting next to him. The father said, “Obey Abu Al-Qasim,” and so the boy embraced Islam. The Prophet صلى الله عليه وسلم came out saying: “All praise is due to Allah who saved the boy from the Hell-fire.”
[Sahih Bukhari, Volume 2, Book 23, Number 438]
عَنْ أَنَسٍ ـ رضى الله عنه ـ قَالَ كَانَ غُلاَمٌ يَهُودِيٌّ يَخْدُمُ النَّبِيَّ صلى الله عليه وسلم فَمَرِضَ، فَأَتَاهُ النَّبِيُّ صلى الله عليه وسلم يَعُودُهُ، فَقَعَدَ عِنْدَ رَأْسِهِ فَقَالَ لَهُ ” أَسْلِمْ ”. فَنَظَرَ إِلَى أَبِيهِ وَهْوَ عِنْدَهُ فَقَالَ لَهُ أَطِعْ أَبَا الْقَاسِمِ صلى الله عليه وسلم. فَأَسْلَمَ، فَخَرَجَ النَّبِيُّ صلى الله عليه وسلم وَهْوَ يَقُولُ الْحَمْدُ لِلَّهِ الَّذِي أَنْقَذَهُ مِنَ النَّارِ
