It was said: "The repentance of Adam was accepted for five reasons, and the repentance of Iblis was not accepted for five reasons. As for the repentance of Adam, then it was accepted because he admitted his sin, regretted it, blamed himself, was quick to repent, and did not lose hope of attaining Allah's Mercy. As for Iblis, then his repentence was not accepted because he refused to admit that he had committed a sin, he did not regret it, did not blame himself, was not quick to repent, and lost hope in attaining the Mercy of Allah. Therefore, whoever's situation is similar to that of Adam, then his repentance will be accepted. Likewise, whoever's situation is similar to that of Iblis, then his repentence will not be accepted."
['Tanbih ul-Ghafilin' (Informing the Heedless) - Imam Abul-Layth Nasr as-Samarqandi]
هَلْ جَزَاء الْإِحْسَانِ إِلَّا الْإِحْسَانُ؟
Is there any reward for good other than good?
[ar-Rahman: 60]
"
However, keep in mind that you must instruct the people with kindness and mercy. Don’t take this answer and shove it in their faces. Be kind, gentle and patient." -
Imam Suhaib Webb, advising after giving an answer.
O Allah, Lord of Jibril, Mika'il and Israfil, Creator of the heavens and the earth, Knower of the unseen and the seen, You will judge between Your servants concerning that wherein they differ. Guide me with regard to that wherein there is dispute concerning the truth by Your leave, for You guide whomsoever You will to the straight path.
Oh Allah, I seek refuge in You lest I misguide others, or I am misguided by others, lest I cause others to err or I am caused to err, lest I abuse others or be abused, and lest I behave foolishly or meet with the foolishness of others.
