On the authority of Abu Hurayrah, who said: The Messenger of Allah, peace and blessings be upon him, came to the grave of his mother, and he wept and made those around him weep. The Messenger of Allah, peace and blessings be upon him, said: "I asked my Lord, Glorified and Exalted, for permission to seek forgiveness for her, and I was not granted permission. And I asked Him for permission to visit her grave, and He granted me permission. So visit the graves, for they remind one of death." (1)

3235 - Ahmad ibn Yunus narrated to us, Mu'arraf ibn Wasil narrated to us, from Muharib ibn Dithar, from Ibn Buraydah, from his father, who said: The Messenger of Allah, peace and blessings be upon him, said: "I had forbidden you from visiting graves, but now visit them, for in visiting them there is a reminder."

(1) Its chain of transmission is sound, except that Yazid ibn Kaysan is in it, and he is trustworthy with no harm in him.
It was also recorded by Ibn Majah (1569) and (1572), and al-Nasa'i (2034) via the path of Muhammad ibn Ubayd al-Tanafisi, with this chain. The wording of the first narration of Ibn Majah is abbreviated with the wording: "Visit the graves, for they remind you of the Hereafter."
It is also in the "Musnad" of Ahmad (9688), and the "Sahih" of Ibn Hibban (1572).

(2) Its chain of transmission is authentic. Ibn Buraydah: he is Abdullah.
It was also recorded by Muslim (977), and Abu Dawud (1975), and al-Nasa'i (2532), (4429), (5652), and (5653) via the path of Muharib ibn Dithar; and Muslim (977) via the path of Ata' al-Khurasani; and al-Nasa'i (2033) via the path of al-Mughirah ibn Subay'; and (4430) and (5651) via the path of al-Zubayr ibn Adi — all four of them from Ibn Buraydah, with it. His name has come specified in some narrations of Muharib and in the narration of Ata' and al-Mughirah as Abdullah.
It was also recorded by Muslim (977) and al-Tirmidhi (1076) via the path of Alqamah ibn Marthad, from Sulayman ibn Buraydah, with it. So he named him Sulayman, and he is the brother of Abdullah.
It is also in the "Musnad" of Ahmad (22958) and (23016), and the "Sahih" of Ibn Hibban (3168), (5390), and (5400), and it will be repeated under number (3698).
