Rasulullah (sallallahu ‘alayhi wa sallam) once passed a grave and asked, ‘Who is buried here?’ The Sahabah (radiyallahu ‘anhum) replied, ‘So and so person.’ Nabi (sallallahu ‘alayhi wa sallam) thereupon said, ‘Offering two rak’ahs of Salah is more beloved to him than your entire world.’
Imam Tabarani (rahimahullah) has recorded this narration on the authority of Sayyiduna Abu Hurayrah (radiyallahu ‘anhu).
(Al Mu’jamul Awsat, Hadith: 924)
‘Allamah Mundhiri (rahimahullah) has declared the chain sound (hasan) and ‘Allamah Haythami (rahimahullah) has declared the narrators reliable (thiqat).
