"Oh, my sons! All of you go and enquire about Yoosuf and his brother and you shouldn't despair about Lord Allah's soothing Mercy; indeed no one despairs about the relief from Allah except the disbelieving people".
Verse 39: 53 says: “My servants who have acted extravagantly against their soul don’t despair of Lord’s mercy; indeed Lord Allah forgives all offenses, He is the Oft-Forgiving, the Merciful. As per verses 39: 54-55 there are two conditions provided for getting forgiveness: (1) To turn towards the Lord with soul and submit all will and power into Him before death happens; (2) To follow the Best Book—Husna—before unexpected death comes. The aimless hypocrites and their heedless followers are reading these verses, but by rejecting Adhikr-the Three-Time-Knowledge-they are earning the Hellfire as explained in verses 2: 254 and 9: 80-82. These disbelievers, wrongdoers, and Mujirims will blame, curse and argue each other in Hell as explained in verses 2: 165-167. See explanation 10: 17-18, 57-58 and 11: 120.
