What should we do at night besides the night vigil (qiyam al-layl)? Thank you.

Night begins with sunset and ends with the true dawn. It is utilized for the Maghrib and 'Isha prayers, as well as for night vigil (Qiyam al-Layl) and Witr. It can also be used for reading, seeking knowledge, attending lectures, visiting kin, or working. The Prophet, peace and blessings be upon him, "disliked sleep before 'Isha and conversation after it" that contained no benefit.
