Riyad as-Salihin #221

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." .
