What Is Qiyam-ul-Layl and Why Is It Important in Islam?

Qiyam means standing. In Islamic terminology, Qiyam refers to standing during prayer while worshipping Allah Almighty, especially while reciting the Holy Qur’an.

A special form of Qiyam is Qiyam al-Layl, which means performing voluntary prayers (such as Tahajjud) at night.

Importance:

Qiyam is a fundamental part of prayer, and without it the obligatory prayer is not complete (for those who are able to stand). 

Similarly, Qiyam al-Layl is one of the best ways to gain closeness to Allah, forgiveness of sins, and inner spiritual peace.
