Your Lord knoweth best what is in your hearts........

In Al-Mahasin it is narrated that regarding God's statement: "Your Lord knoweth best what is in your hearts: if you do deeds of righteousness, verily He is Most Forgiving to those who turn to Him again and again (in true penitence). "[The Holy Quran: Bani Israil 17:25]

Imam Sadiq (a.s) said: "They are the ones who worship a lot and repent often." 

Ameer al-Momineen (a.s) said: "Whenever one repents and God the Almighty accepts his repentance, God will employ his body parts to cover up his sins. God will employ the places where the sins were committed to hide the sins, and will make the guardian angels who record the sins forget them." 

Imam Sadiq (a.s) quoted on the authority of his grandfather (a.s) on the 

authority of God's Prophet (a.s): "Whenever you repent, God the Almighty will be pleased just as you get happy when you find something that you have lost." 

Imam Sadiq (a.s) said: God the Almighty has granted those who repent three things each one of which could save all that lives on the Heavens and on the Earth, if it were granted to them: 

(1) God the Almighty said: "For Your Lord knoweth best what is in your heartsand He loves those who keep themselves pure and clean. "[The Holy Quran: Baqara 2:222]; Therefore God will not punish whomever He loves. 

(2) God the Almighty said: "Those who sustain the Throne (of God) and those around it sing Glory and Praise to their Lord; believe in Him; and implore Forgiveness for those who believe; "Our Lord! Thy Reach is over all things, in Mercy and Knowledge. Forgive, then, those who turn in repentance, and follow Thy Path; and preserve them from the Penalty of the Blazing Fire! "And grant, our Lord, that they enter the Gardens of Eternity, which Thou hast promised to them, and to the righteous among their fathers, their wives, and their posterity! For Thou art (He), the Exalted in Might, full of Wisdom. And preserve them from (all) ills, and any whom (Thou) dost preserve from ills that day, on them will Thou have bestowed Mercy indeed: and that will be truly (for them) the Highest Achievement." [The Holy Quran: Mu-min 40:7-9]. 

(3) God the Almighty said: "Those who invoke not, with God, any other god, nor slay such life as God has made sacred, except for just cause, nor commit fornication, and any that does this (not only) meets punishment (but) the Penalty on the Judgment Day will be doubled to him, and he will dwell therein in ignominy, unless he repents, believes and works righteous deeds, for God will change the evil of such persons into good, and God is Oft-forgiving, Most Merciful." [The Holy Quran: Furqan 25:68-69] 

Imam Sadiq (a.s) quoted on the authority of God's Prophet (a.s): "God shall accept the repentance of whoever repents one year before he dies." Then he said: "One year is too long. God shall accept the repentance of whoever repents one month before he dies." Then he added: "One month is too long. God shall accept the repentance of whoever repents one week before he dies. "Then he said: "One week 

is too long. God shall accept the repentance of whoever repents one day before he dies." Then he said: "One day is too long. God will accept the repentance of whoever repents before he faces death."
