Conditions of sincere repentance
The conditions of repentance are: Firstly to regret what one did and fear God deep in heart.
He should also abandon sins at once; if he repents and soon goes back to sins again, this is derision to his Lord. He should leave sins at once and intend faithfully not to go back to them if these sins are between him and God.
If a sin is a right of people, he should give it back to that person if it is money and the owner is alive or has heirs, then he should give it back to him or to his heirs. If he doesn’t know where the owner gone or where are his heirs, then he should give it as a charity on his behalf. If he backbit someone in a sitting, he should praise and compliment him in the same sitting so that the good deeds erase the bad deeds as God says:
11-114: “For those things that are good remove those that are evil.”
In each sitting where he insulted him, he should praise him to expiate his sin.
Imam Asheply was a governor of a part of Iraq; God granted him beauty of righteous people and secrets of the people of nearness. When he was about to die, he cried too much, they asked him why he was crying, he said: “By God, I don’t cry for sins, I never done any sin," they asked him: "Then why do you cry?" He said: "Because I took one dirham illegally from a man when I was a governor, I searched for him for years but I didn’t find him, then I gave charity by thousands on his behalf, but I still fear he asks me his dirham on the Day of Judgment.” These are the conditions of righteous people, Oh brothers.
Do you want to be one of good and righteous people while you extort rights from people and needy here and there?
This is impossible, Oh brothers. We should follow the messenger of God, the prophet himself, (May the blessing and peace of God be upon him), stood before a battle amongst his relatives, lovers and followers and said to them:
“Oh people, soon I am going to die, anyone I whipped his back, this is my back, come and take revenge. Anyone I insulted him, this is my honor, come and take revenge. Anyone I took his money, this is my money, come and take revenge.”
If this is the messenger of God, (May the blessing and peace of God be upon him), who said in another Hadith:
“Oh my Lord, I trust You will not break my covenant, I am human, if I harmed, insulted, whipped or cursed any believer, make it as prayer, charity and a good deed for him in the Day of Judgment.”
His supplication is responded for sure, however he asks his brothers to pardon him, then what should we do? We should follow his guidance, (May the blessing and peace of God be upon him) in this because giving people’s rights to them is a condition for God’s love, God says:
2-222: “For Allah loves those who turn to Him constantly and He loves those who keep themselves pure and clean.”
Oh brothers, this is the interpretation of righteous people and this is what Imam Abul-Aza’em agreed to it because God says:
25-70: “For Allah will change the evil of such persons into good,”
What we said now is their interpretation of this verse:
When someone does a sin and he wants God to forgive him, he should do a good deed as we said before. If he backbit someone in a sitting, he should praise him in the same sitting. Some people think that God changes evil deeds to good deeds without returning rights to people, this is wrong, if he takes the right of someone, he should give it back to him so that God changes his evil deeds to good deeds. If he abuses someone, he should ask him to pardon and forgive him. Whenever he wants God to forgive a sin, he should do a good deed so that God pardons him and changes his evil deeds to good deeds. Some people wrongly understand that God changes all the sins in his records into good deeds! The fact is that you are the person who changes, as God says:
13-11: “Verily never will Allah change the condition of a people until they change it themselves (with their own souls).”
If you insulted someone and he complained to God and you repent to God and even did Hajj to Ka’ba but you don’t ask forgiveness of this person, how God changes this sin into a good deed while that person still want his right.
You should introduce him a favor so that he can forgive and pardon you, then God changes the sin into a good deed because you did the good deed by which He forgives your sin. When a repentant realizes these meanings, he watches himself, his movements and his stillness. He rationalizes his words and codifies his deeds and movements so that he doesn’t say things that get people angry and then he gets confused in life and in the hereafter. He doesn’t do anything that he can never return.
What makes righteous people follow the straight path?
They question themselves about words, deeds and intentions because bad intentions are kinds of sins which need repentance. God says:
2-284: “Whether you show what is in your minds or conceal it, God calls you to account for it,”
They should think of a good intention so that God forgives the first bad intention by good intention, this is what righteous people do. Does repentance occur just by saying: "I repent to God; I return to God, I regret what I did?" No, it can be done for someone whose record doesn’t have any case, misdemeanor or felony ….etc.
Truthful believers always try to change what inside their souls, so if you look at the struggles of righteous people, you will see astonishing things. Why?
Because they struggle in revising sins and defects and they try doing deeds by which they deserve God’s satisfaction. They do such deeds so that they get God’s satisfaction.
 Jame'a Al-Ahadeeth Wal-Maraseel, Al-Awsat and Abu-Ya’ly after Al-Fadl Ibn-Abbas, the completion is: “No man should say: I never dispute against the messenger of God, dispute is not my nature or my ethics, the most beloved to me amongst you is that who seeks his rights or pardon me so that I meet God pure. I insist on saying again and again: Oh people, whoever has illegal thing he should give it back and doesn’t fear scandal in this life, as scandal in this life is easier than scandal in the hereafter”
 It was narrated in Mosnad of Imam Ahmed after Hammam Ibn –Monabbeh, he said that Abu-Horayrah told it to him.
