This righteous person beseeches and supplicates to Allah through this door; the door of mercy

saying: “O Allah, you say “But whoever repents after his wrongdoing and reforms, indeed, Allah will turn to him in forgiveness. Indeed, Allah is Forgiving and Merciful.” (Al-Ma’idah 5:39)

And here I have repented of my wrongdoing, so have mercy on me”

He beseeches Allah with this!

“And if I am not worthy of it, you said: “and He is ever Merciful to the believers” (Al-Ahzab 33:43)

And I am a believer, so have mercy on me.

And if I am not worthy of it, you said: “but My mercy encompasses all things” (Al-A`raf 7:156)

And I am a thing, so have mercy on me.

And if I am not worthy of it, then there’s no calamity greater than mine!

The mercy that encompasses all things does not compass me

This is sure to be a calamity! Now I say, as You taught us, “Indeed we belong to Allah, and indeed to Him we will return.” (Al-Baqarah 2:156)

And you says: “Who, when afflicted with calamity, say: Indeed we belong to Allah , and indeed to Him we will return. Those are the ones upon whom are blessings from their Lord and mercy.” (Al-Baqarah 2:156-157)

and hence, bestow your mercy on me.”

He beseeches Allah by all means.

By means of His Attributes: the Merciful, the Beneficent.
