What are the answers to the following questions concerning Islam: 1. Does Allah forgive everything, with details on forgiveness before and after death, and does Allah accept the good deeds of polytheists? 2. Does Allah know everything? 3. How can one believe in Allah despite not seeing Him? 4. Are there any specific departments or offices in Portugal for those who have questions about Islam?

Whoever repents from polytheism and disbelief and embraces Islam, all his sins are forgiven, and his evil deeds are transformed into good deeds, because Islam nullifies what came before it. As for whoever dies a polytheist, he will not be forgiven, and his good deeds will not benefit him.

And Allah's knowledge encompasses everything in the heavens and the earth, outwardly and inwardly. He knows what was, what is, and what will be. He is the Subtle, the All-Aware, the Creator of all things. As for the existence of Allah, it is indicated by His cosmic signs dispersed throughout the souls and the horizons.
