Men were punished by transforming into Monkeys for transgression of Allah's commands...

 Men to Monkeys

The Quran does mention a story involving a group of people who faced a punishment from Allah for their disobedience, but it does not involve any transformation into animals.

One such story is mentioned in Surah Al-Baqarah (Chapter 2), verse 65, which talks about the Israelites during the time of Prophet Moses (Musa in Arabic). The verse states:

"And certainly, you have known those among you who transgressed in the matter of the Sabbath. We said to them: 'Be you monkeys, despised and rejected.'"

In this verse, Allah recounts how some of the Israelites violated the sanctity of the Sabbath by fishing on that day, despite being commanded not to do any work on the Sabbath. As a consequence of their disobedience, Allah punished them by transforming them into monkeys, both as a sign of His disapproval and as a lesson for others.

It's important to note that the Quran provides these stories as historical accounts and lessons for humanity, but they are not meant to be taken as literal events that regularly occur. The primary purpose is to convey moral and spiritual teachings for believers to reflect upon and learn from.
