Sahih al-Bukhari
Prayer at Night (Tahajjud)
Chapter: The Prophet's (pbuh) exhorting to Tahajjud and Nawafil without making them compulsory
Narrated `Aisha:
Allah's Messenger (ﷺ) used to give up a good deed, although he loved to do it, for fear that people might act on it and it might be made compulsory for them. The Prophet (ﷺ) never prayed the Duha prayer, but I offer it.
