Sunan Ibn Majah, Book 6, Hadith 1640 (In-Book) ⓘ

It was narrated from Salim that his father said: “A Bedouin came to the Prophet and said: ‘O Messenger of Allah, my father used to uphold the ties of kinship, and so and so forth, where is he?’ He said: ‘In the Fire.’ It was as if he found that difficult to bear. Then he said: ‘O Messenger of Allah. Where is your father?’ The Messenger of Allah said: ‘Whenever you pass by the grave of an idolater, give him the tidings of Hell-fire.’ The Bedouin later became Muslim, and he said: ‘The Messenger of Allah gave me a difficult task. I never passed the grave of an idolater but I gave him the tidings of Hell-fire.’”
