It was narrated that Abu Hurairah said: “The Prophet (ﷺ) visited the grave of his mother and wept, causing the people around him to weep. Then he said: ‘I asked my Lord for permission to seek forgiveness for her, but He did not give me permission. Then I asked my Lord for permission to visit her grave and He gave me permission. So visit the graves, for they will remind you of death.’”

It was narrated from Salim that his father said: “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.’”
