Say, “O My slaves who have violet against themselves [by sinning], do not lose hope in the mercy of Allah. Indeed, Allah forgives all sins. Indeed, it is He who is the Forgiving, the Merciful.” (Qur’an 39:53)
There is an extremely important lesson in this ayah. Allah Subhanahu Wa Ta`ala tells the Messenger Muhammad (peace and blessings of Allah be upon him) to speak to His servants who immersed in sins that we must turn back to Allah and never lose hope from Allah. We need to always remember that our Rabb is the Most Merciful and Most Compassionate (al-Rahman, al-Rahim). Allah Most High tells us in the Qur’an to never lose hope in Him, regardless of how badly we stumble, fall, err, or sin.
He is extremely forgiving. Those have gone beyond limits and disobey Allah only harms their own selves. No one can harm Allah and take anything from Him.
Even if we are immersed in sin, Allah still talks to us and says: “My slaves. (Ya ibaadi.)” This is a sign of love and mercy. Allah (SWT) calls us by a good name. He still cares us and takes us seriously. No matter how much we fall into sin, we are still His slave. There’s still hope alive for us. No doubt that He is the most merciful. He loves His slaves more than a mother does her child.
Thus we need to never lose hope in Allah’s mercy. His doors are always open. We should not avoid Him. We need to turn back to our Master. We should talk to Allah (SWT). Allah hears us and our duas. We need to swear to give up haram things (make tauba-repentance). And we should not to maintain those harams and sins. Despite all that we did, He still says “Don’t lose hope in My mercy.” No doubt Allah will forgive all of the sins, altogether.
“Declare (O Muhammad) unto My slaves, that truly, I am the Oft-Forgiving, the Most-Merciful.” Qur’an 15:49
It is narrated that the Prophet (peace and blessings of Allah be upon him) said: “Allah has one hundred parts of mercy, of which He sent down one between the jinn, mankind, the animals and the insects, by means of which they are compassionate and merciful to one another, and by means of which wild animals are kind to their offspring. And Allah has kept back ninety-nine parts of mercy with which to be merciful to His slaves of the Day of Resurrection.” (Muslim, al-Tawbah, 6908)
He is Raheem. He is extremely forgiving and always merciful. However we are not allowed to whatever we want to do. We have to be aware He’s not always forgiving. He’s extremely forgiving but even when He punishes. We don’t take advantage of thinking Allah’s always going to forgive.
And the Messenger of Allah (peace and blessings be upon him) promised that, “The one who repents from sin is like one who never sinned.” [Ibn Maja]
“Hurry towards your Lord’s forgiveness and a Garden as wide as the heavens and earth prepared for the righteous, who give, both in prosperity and adversity, who restrain their anger and pardon people– God loves those who do good– those who remember God and implore forgiveness for their sins if they do something shameful or wrong themselves– who forgives sins but God?– and who never knowingly persist in doing wrong. The reward for such people is forgiveness from their Lord, and Gardens graced with flowing streams, where they will remain. How excellent is the reward of those who strive!” (Qur’an, 3.134-136)
