Would Allah Forgive me?Please

Walaikum Salaam,

What you did is indeed a great sin. Allah has created us to worship him and he tests his slaves by diseases, loss of wealth, health, unexpected accidents etc. We will not live forever in this world and will have to go back to the place we came from.

You should read the biography of our prophet Mohammad(PBUH) and also about other prophets of Islam. Allah loves them the most. Do you think they lived a very wealthy and easy life?

The good thing is you have realized your sins Alhamdulillah. Repent to Allah sincerely. Inshaallah you will be forgiven by the almighty.
