How sound is the Hadith: "My servant, I remind you, yet you forget Me; I conceal your sins, yet you do not fear Me. Had I commanded the earth, it would have swallowed you in its belly; or the seas, they would have drowned you in their depths. But I defer you until a term I have appointed and a time I have set. And surely, you and every soul must pass by Me and stand before Me. I will enumerate your deeds to you and remind you of your actions, until, when you are certain of ruin and realize you are among the people of the Fire, I will bestow My forgiveness upon you and grant you My pleasure, and I will say to you, 'Do not grieve, for I have forgiven your sins and burdens.' And for your sake, I named Myself Al-Aziz, Al-Ghaffar (The All-Mighty, The Ever-Forgiving)"?
