Committing sins
Q:
1) I heard many times from many people that if you satisfy your sinful desires in this world like drinking wine, wearing silk etc, these desires will be taken out from you in Jannah, is that true?
2) I thought even if you commit sinful acts or desires like drinking wine, wearing silk, if you repent you are forgiven so if you repent would Allah still take away these desires from you?
3) What worries me that if I drank wine, wore silk clothes, ate on gold plates etc I wouldn't do these things in jannah (paradise), if I committed those things, if I repent would that be enough?
4) Does Allah forgives sins if you repent without namaaz?or you have to pray namaaz to get your sins forgiven of drinking wine, wearing silk clothes?
