Riyad as-Saliheen 900
Anas (May Allah be pleased with him) reported:
A young Jewish boy who was in the service of the Prophet ﷺ fell ill. The Prophet ﷺ went to visit him. He sat down by his head and said to him, "Embrace Islam." The little boy looked at his father who was sitting beside him. He said: "Obey Abul-Qasim (i.e., the Messenger of Allah ﷺ)." So he embraced Islam and the Prophet ﷺ stepped out saying, "Praise be to Allah Who has saved him from Hell-fire."
وعن أنس رضي الله عنه قال: كان غلام يهودي يخدم النبي ﷺى الله عليه وسلم الله عليه وسلم فمرض فأتاه النبي ﷺ الله عليه وسلم الله عليه وسلم يعوده، فقعد عند رأسه فقال له: "أسلم" فنظر إلي أبيه وهو عنده؟ فقال: أطع أبا القاسم، فأسلم، فخرج النبي ﷺى الله عليه وسلم الله عليه وسلم وهو يقول: “الحمد لله الذي أنقذه من النار” ((رواه البخاري)).
