Wear white garments when visiting mosques and graves.

According to a hadith narrated by Abu Darda, the Prophet Muhammad (PBUH) taught us that wearing white garments is best when visiting mosques and graves. This hadith emphasizes the importance of modesty and humility when engaging in religious activities such as prayer or visiting holy sites. Wearing white can be seen as a sign of purity and respect for Allah's house. It also serves as a reminder that we should strive to purify our hearts from any negative thoughts or feelings before entering these places. Additionally, this hadith teaches us that we should always dress modestly whenever we are engaging in religious activities so that our focus remains on worshipping Allah rather than on worldly matters such as fashion or trends.
