Musnad Ahmad 3926

It was narrated from Abu 'Ubaidah bin ‘Abdullah bin Mas'ood, 'Affan said: that his father Ibn Mas'ood said: Verily Allah sent His Prophet (ﷺ) to be the cause of a man entering Paradise. He entered the synagogue and saw some Jews, and a Jew was reading the Torah to them. When they came to a description of the Prophet (ﷺ), they stopped reading. There was a sick man in the gathering, and the Prophet (ﷺ) said: "Why did you stop reading?" The sick man said: They came to a description of a Prophet, so they stopped reading. Then the sick man came crawling until he took the Torah and read until he came to the description of the Prophet (ﷺ) and his ummah. And he said: This is a description of you and your ummah; I bear witness that there is no god but Allah and that you are the Messenger of Allah. Then he died, and the Prophet (ﷺ) said to his companions: "Take care of your brother."
