Sahih Bukhari

Narrated `Abdullah bin `Amr bin Al-`As:Allah's Messenger (ﷺ) said, ""O `Abdullah! Have I not been formed that you fast all the day and stand in prayer all night?"" I said, ""Yes, O Allah's Messenger (ﷺ)!"" He said, ""Do not do that! Observe the fast sometimes and also leave them (the fast) at other times; stand up for the prayer at night and also sleep at night. Your body has a right over you, your eyes have a right over you and your wife has a right over you
