The Prophet (sallallahu alayhi wa sallam) said: "Whoever says 'Subhanallahi wa bihamdihi' three hundred times on the day of Eid and dedicates it to the deceased Muslims, light will enter every believer's grave, and when the person dies, Allah will provide a thousand lights for his grave."
(Tabarani, al-Mu'jam al-Awsat, 1/357)
