Practice your faith with dedication and devotion even when no one else knows what you are doing.

This hadith speaks to the importance of fasting in Islam. It is narrated by Yazid Ar-Rishk that Mu'adhah asked Aishah if the Messenger of Allah used to fast three days out of every month. Aishah replied in the affirmative, but noted that it was not noticeable which days he would fast. This shows us how dedicated and devoted the Prophet Muhammad was to his faith, as he consistently practiced fasting even when no one else knew about it. It also serves as an example for us to follow; we should strive to practice our faith with dedication and devotion even when no one else knows what we are doing.
