If a man decides after a life of sinfulness to come to God and promise to reform his life, I understand that Islam says that he will be forgiven and therefore inherit the promises etc.
My question though is what has happened to the weight of this man's sin, as in sinning he has offended God and therefore this sin has to be atoned for; who is going to atone for his sin, if God is just going to forgive him on the promise of his being good and faithful? Surely as we saw with Adam there has to be a consequence for sin...

There are many religions.

Why do Muslims think that Islam is true. Is there any factual basis?

I have committed many sins which no one knows of except Allaah. What do I have to do so that Allaah will accept my repentance?

A brother of ours has recently become Muslim. During his days of Jaahiliyyah (ignorance – i.e., before he became Muslim), he earned a lot of money by dealing in drugs. He brought this money with him and opened a big bookstore and got married using this money. Recently he has been told that it is not permissible for him to give this money in charity, because Allaah is Good and only accepts that which is good, Our question is, what should he do with this money, and how sound is what he has been told?.

How should we call people to Islam?

I am one of those who send blessings upon the Prophet between 50 and 100 times a day, according to circumstances. I say: “Allahumma salli ‘ala Muhammadin wa aali Muhammad (O Allah, send blessings upon Muhammad and the family of Muhammad).” There are some people who tell me that my sending blessings upon the Messenger of Allah is lacking. Can you tell us – may Allah reward you with good – what is the ideal way to send blessings upon the master of mankind, and is the way I am doing it really lacking?

How can we prove to non-Muslims that Islam is a tolerant and easy religion?

If a person slept through Fajr prayer, will Allaah reward him for the remainder of the prayers on that day, or not? And if he prays it after he wakes up, will it be accepted from him?

If a man was praying the sunnah of the fajr [prayer], or other than it, and whilst doing so the [iqaamah for the obligatory] prayer was called, is he required to [promptly] terminate his prayer in order to join the imaam [and congregation] in [the obligatory] prayer, or should he complete his prayer [first]?

Who do Muslims worship?

One of the guys at work was asking me why I became Muslim and I told him it is the path I must follow. I don’t know sometimes what I should say, for me it is the path I must follow. What can I say to someone; I don’t want to push what I believe, so how should I answer someone if asked, what is the right way to answer the questions? Sometimes I feel I don’t give the right answers... Any clues as to what I can say?

According to the Quran and/or Islamic traditions, why did God create mankind?
