Worship Allah sincerely without any intention for show-off or gaining recognition from others.

This hadith warns us about a sign of the end times which is people showing off in building mosques. It is important to remember that our actions should not be done for show or to gain recognition from others but rather out of sincerity and faith. We should not build mosques just to show off our wealth or status but instead we should focus on worshipping Allah and following His commands with humility and sincerity. We must also remember that it is not only about building physical structures but also about having a strong spiritual connection with Allah through prayer and worship.
