Hadhrat Abbas (radhiyallahu anhu) narrates: “A year after Umar’s demise, I supplicated to Allah for him (Umar) to appear in my dream. Thus, after a year I saw him in a dream wiping the perspiration from his forehead.
I said: ‘May my mother and father be sacrificed for you! O Amirul Mu’mineen! What is this condition?’ He replied: ‘I have just now been released (from the Reckoning). I was close to destruction, but I found Allah Ta’ala Most Merciful.’ ”
