That is the reason why repentance must take place before death to be valid, that is, it must take place where there is still time and opportunity for it. God says in the Quran, He promises them and fills them with fancies but there is nothing satan promises then? except delusion. (4: 120) A man came to Hadrat Imam Ali (as) to repent and when the Imam realized that the man was ignorant of the importance of repentance, he said to him, "Do you know the meaning of repentance?
It has an exalted position. It has six conditions for its acceptance and the last two are the conditions of its completion." What are those six points? The first one is regretting what has passed. It means looking at the dark deed and being so sorry and ashamed of it that it makes your heart burn. The Quran says, Oh believers, wine and arrow-shuffling, idols and divining arrows are an abomination, some of satan's work, so avoid it; haply you will prosper.
(5:90) Everyone knows how despicable dead flesh is and there is nothing more fitting than comparing backbiting with it. Calumny is in the same category of sins. Some people in accusing others begin their words by the phrase, "It is said," and suppose that in this way they acquit themselves of the sin of calumny and later on they disclaim their remark and say that they have quoted others' words. This too is a sin and the Quran has forbidden it in the following verse.
Those who love that indecency should be spread abroad concerning those who believe there awaits them a painful chastisement. (24:19) Those who spread accusations of others are committing a great sin. The same applies to unclean glances at people's wives or daughters to the abandonment of prayer and fasting and showing indifference to sacred rites in the months of mourning and fasting. Being inadequately dressed in public is another such sin.
The Prophet in speaking of his ascension says, "I saw women there hung by their hair and beaten with fiery scourges and women who were hung by their breasts and beaten with whips. I asked who they were and was told, "These are the women who exhibited their bodies in public." Of what worth is this brief span of life to expose oneself to such heavenly punishments. Is it not time to come to oneself, to feel humble and show interest in what is ordained by God?
