“A Bedouin came to
the
Prophet (ﷺ) 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 (ﷺ) 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 (ﷺ)
gave me a difficult
task. I never passed the grave of an idolater but
I gave him the
tidings of Hell-fire.’”
Sunan Ibn Majah Book 6, Hadith 141
