question #1 Sahih al-Bukhari 1987, Book 30, Hadith 94 : What can be learned about the consistency in worship from the practices of the Prophet Muhammad (ﷺ)?

I asked `Aisha “Did Allah s Apostle, use to choose some special days (for fasting)?” She replied, “No,
but he used to be regular (constant) (in his service of worshipping). Who amongst you can endure
what Allah’s Messenger (ﷺ) used to endure?”
