What deeds illuminate a Muslim's grave?

What illuminates a Muslim's grave are all good deeds, especially prayer and patience, due to the Almighty’s saying: “And seek help through patience and prayer,” and the Prophet’s (peace be upon him) saying: “And prayer is light, and charity is a proof, and patience is a radiance.” Likewise, supplication illuminates the grave, for the Prophet (peace be upon him) supplicated for Abu Salama: “And expand for him in his grave, and illuminate it for him therein.” And among the wordings of the funeral prayer is: “O Allah, illuminate his grave for him.”
