Worship only Allah; Think before speaking/acting; Give charity when invited for gambling .

This hadith is about avoiding idolatry and gambling. It was narrated by Abu Huraira, who said that the Prophet Muhammad said that if someone takes an oath in the name of two idols worshipped by pagans, they must say "None has the right to be worshipped but Allah". He also said that if someone invites their friend to gamble with them, they must give something in charity. This hadith teaches us to avoid taking oaths in the names of false gods or deities as well as gambling. Instead, we should focus on worshipping Allah alone and giving charity when we can. We can also learn from this hadith that it is important to think before we speak or act so that our words and deeds are pleasing to Allah.
