You talk many times about following the last Prophet in many threads, so what are the guidances of muhammed you have followed or believers in muslim majority countries are following?
Many of the things Allah has commanded the last prophet to convey are almost similar to what the previous prophets brought from God.
All the 10 Commandments apply.
Acknowledge and Worship One Allah
Don't take partners for Him
Don't take images, idols, and animate or inanimate objects as god.
Fast.
Charity
Hajj
Responsibilities.
Put in effort in what you pursue, but leave the outcome to Allah's discretion, for only He knows best what is for you.
Patience.
Stay away from taking or giving usury.
Forbid evil, enjoin good wherever you see it.
Many more dos and don'ts but it's all for the benefit of the individual and the society at large.
Ask me more specific things. Maybe I can answer.
