Bismillahir Rahmaanir Raheem
1.) Rasulullah Sallallaahu ‘alayhi wasallam said: “Visit the graves, for verily, the graves remind you of the Aakhirah (Hereafter).”
2.) Hadhrat Buraidah (Radhiyallahu ‘anhu) reported that Rasulullah Sallallaahu ‘alayhi wasallam would teach the Sahabah (Radhiyallahu ‘anhum) that, ‘When they enter the graveyard, they should greet its inhabitants with the following words, ‘Peace be upon the Believers among those in the graves, and surely through the will of Allah Ta’ala, we will soon join you. We ask Allah for (eternal) well-being for us and for you.’
Similar versions of this Dua appear in different Hadith narrations.
3.) Rasulullah Sallallaahu ‘alayhi wasallam used to visit the graveyard of Al-Baqi’ in Madinatul Munawwarah and make Dua for those buried there.
4.) Whenever Hadhrat Uthman (Radhiyallahu ‘anhu) stopped at a graveyard, he would weep so much that his beard would get wet. Someone once asked him: “You do not weep when you think of Jannah and Jahannam but weep when you think of the grave?”
He replied: “I have heard Rasulullah Sallallaahu ‘alayhi wasallam say: ‘The grave is the first stage from amongst the many stages of the Aakhirah (Hereafter). If one is successful there, the later stages are easier. However, if one is unsuccessful there, the later stages will be extremely difficult.’ I have also heard Rasulullah Sallallaahu ‘alayhi wasallam say that he had never seen a sight more frightening than that of the grave.”
