sin

Q: I had heard an incident of the past wherin 3 people where closed in a cave and they each looked at a sinful act of their past to which they abstained and then asked Allah to move the rock blocking the entrance and Allah accepted.

This made me think and some weeks later in a depressed state whilst making dua to Allah, I said such, Oh Allah I will try my best no promises to abstain from this sin, please let me be married now. If I lapse into this sin again will I be accountable now for 2 sins.

1. The sin itself

2. Not abstaining. wrong

I am still not married. Please assist me. I am concerned that I unknowingly might have committed a vow and now I don't know what to do.

Q: Is taking a loan a sin and if it is a sin then what is the punishment if the loan is taken?

Q: If a married couple is not happy, will the one who breaks the marriage get the sin?

Q: I am suffering from waswasa for a long time. In Islam every thing is about intention, but I am not sure about my intention. So is it a major sin if I have an intention to do a major sin if I had a chance to do? If a person thinks that he is ready to commit a major sin if he had chance to and then asked forgiveness but he didn't do it, is the same sin recorded by thinking about sinning or not?

Q: How to differentiate between sin and shirk (especially major shirk) Example:

1# If a person does many haram acts because of his desire and continues it without fearing Allah then will it be just a sin or it will be considered as he is following his desire? Is it shirk as mentioned in Quran [45:23] “Have you seen he who has taken as his god his [own] desire, and Allah has sent him astray due to knowledge and has set a seal upon his hearing and his heart and put over his vision a veil?

2# We know interest is haram. If a person continues to take interest after knowing it haram or does not pay zakat, does it mean that he loves money more than Allah and doing shirk as mentioned in hadith “He who became the slave of the Dinar or the Dirham will perish and be destroyed.” [Hadith Bukhari] So are these just sin or they are shirk or they may lead to shirk even major shirk?

Q: If I insulted someone in my mind or heart without speaking it out, am I going to get sin?

Q: If someone did a promise with Allah Ta'ala to leave some specific sin in private and no people are of witness to that. If the man did again that sin due to some reason, is there any kaffaara and what type of such promise is this?
