Be humble and respectful when praying to Allah; Act with respect when visiting mosques; Do not show off or boast about your religious practices.

This hadith is about the Prophet Muhammad's practice of reciting talbiyah, a prayer to Allah, while visiting the mosque of Dhu al-Hulaifah. According to this hadith, the Prophet did not raise his voice in reciting this prayer but instead spoke it quietly. This teaches us that we should be humble and respectful when praying to Allah and that we should not show off or boast about our religious practices. We should also remember that mosques are places for peace and contemplation, so we must always act with respect when visiting them.
