Hadis Sambhar — Hadith #38194

Once when the Prophet (peace be upon him) visited his mother's grave, he wept and made everyone around him cry. (Because, when asked) he said, “I am permitted to ask Allah for forgiveness for my mother I wanted But he didn't allow me. Then I asked him for permission to visit his grave, and he allowed it. So visit the graves. Because, it reminds of death.” (Muslim 2304, Abu Dawud 3234, Nasa'i 2033, Ibn Majah 1572)
