Allāh ﷻ created us for His ﷻ pleasure, and He ﷻ likes us to worship Him ﷻ. Qiyāmu l-Layl is the more acceptable and valuable ‘ibādah. It was obligatory for the Prophet ﷺ to make it, but it was made sunnah for his ﷺ ummah because it is so difficult. The night time, is when the servant and Allāh ﷻ are closest. Many are sleeping so late, so it is even more difficult to wake up. But you must make your time and listen to the Prophet ﷺ.
