Follow Islamic teachings and do not be swayed by external influences

This hadith is about the importance of keeping the name of Isha prayer, which is a mandatory part of Islamic worship. It was narrated by Ibn 'Umar that he heard Prophet Muhammad say that one should not change the name of their prayer due to Bedouin influence. This means that even if someone from a different culture or background suggests something different, it should not be followed if it goes against Islamic teachings. The Prophet's warning here shows how important it is for Muslims to stay true to their faith and not be swayed by external influences. It also serves as a reminder for us to always seek knowledge and guidance from reliable sources when making decisions in our lives.
