Narrated Abu Hurairah: The Messenger of Allah صلی اللہ علیہ وسلم visited his mother's grave and wept and cause those around him to weep. The Messenger of Allah صلی اللہ علیہ وسلم then said: I asked my Lord's permission to pray for forgiveness for her, but I was not allowed. I then asked His permission to visit her grave, and I was allowed. So visit graves, for they make one mindful of death.
