Q 1: What is the ruling on
Salat-ul-Layl (optional Prayer at night)?
Is it preferable to perform Witr (Prayer with an odd number of units) during the first part of the night or at the end of it? We usually perform voluntary Salahs during the last part of the night. Guide us, may Allah reward you with the best.
Salat-ul-Layl is Sunnah. It is better for a person who is able to perform Witr during the last part of the night and does not fear missing it by sleeping or the like to do so. The Prophet (peace be upon him) said:
Anyone who fears that they may not get up in the last part of the night, let them offer Witr in the first part of it; and anyone who is eager to get up in the late part of night, let them offer Witr at the end of the night, for Salah at the end of the night is witnessed (by the angels) and that is better.
in his Sahih [Authentic Hadith Book])May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
