Mishkat al-Masabih #1494

Anas told that when a young Jew who was a servant of the Prophet became ill the Prophet went to visit him and, sitting down by his head, said to him, “Accept Islam.” He looked at his father who was beside him, and he said, "Obey Abul Qasim.” So he accepted Islam, and the Prophet went out saying, "Praise be to God who has saved him from hell.” Bukhari transmitted it.
