Question:
What is the ruling on visiting graves on the day of the festival?

Answer:
Visiting graves for the purpose of greeting the Muslims and making du'a for them, especially relatives, is prescribed and recommended. The Messenger (peace and blessings be upon him) commanded it. He said: "Visit the graves, for they remind you of the Hereafter."
The lawful visiting of graves has two objectives. The first is to be reminded of the Hereafter, and the second is to benefit the deceased by making du'a for him, greeting him, and seeking mercy for him. This is a prescribed visit, and it is not tied to a specific day, neither the day of the festival nor any other day. There is no evidence for specifying the day of the festival or Friday.
You may visit the graves at any time, because the Prophet (peace and blessings be upon him) said, "Visit the graves," and he did not specify a particular day.
