Prayer Against Those Who Reject Faith (From Surah Nuh)

The Prophet said believers don't use bad words or curse a lot. Muslims should speak with kindness. Duas for Muslims and Islamic prayers should be done with respect.

Yes. Islam says cursing and swearing are big sins. Harsh words and insults are not good. Focus on dua in Islam and talk with respect.

You can curse disbelievers in a general way. Don't say specific names unless you know they died as disbelievers. Better to say duas from Quran and ask Allah for protection.

Sometimes he prayed against people who hurt Islam. Other times he asked for mercy. This shows Muslims need wisdom and patience when making dua against enemy.

Prophet Nuh spent many years calling people to Allah. They refused to believe. So he made dua against enemies, asking Allah for justice and safety.
