In Ramadan, the night is filled with prayers and devotion to the Creator. After performing the terawih/tarawih prayers (صلاة التراويح), witr (صلاة الوتر) is the usually the final prayer of the night. Here are some quick pointers.
1. When can I perform tarawih?
Anytime between Isya’ and Subuh. (Source)
2. How many rakaat is tarawih performed?
3. Must I perform tarawih in the mosque?
While praying in jama’ah in a mosque is better, one can also do it at home. (Source)
4. Minimum rakaat of witr?
One. But three is preferred. (Source)
5. Maximum rakaat of witr?
6. When do I perform the qunut for witr in Ramadan?
7. After praying witr, can I perform other prayers in the same night?
Long answer: (Translated from source)
Originally, one concludes that his prayers at night with the witr, following the saying of the Prophet ﷺ:
اجْعَلُوا آخِرَ صَلَاتِكُمْ بِاللَّيْلِ وِتْرًا
“Make your last prayer at night witr.”
If a person prayed witr and following that he intends to pray more, there is no harm in doing so. But he shouldn’t repeat the witr, as the Prophet ﷺ said:
لَا وِتْرَانِ فِي لَيْلَةٍ
“No two witr in one night.” (I.e. do not perform witr twice in a night)
– Abu Dawud et al.; categorized sahih by al-Albani
Al-Nawawi said in al-Majmu’ (المجموع):
إذا أوتر ثم أراد أن يصلي نافلة، أم غيرها في الليل، جاز بلا كراهة، ولا يعيد الوتر
“If a person performed the witr, and then he wants to pray the nafilah (i.e. sunnah prayers), or any other prayers at night, it is permissible and not makruh, (but) he should not repeat the witr.”
Meanwhile if he purposely performed the witr earlier in the night, while knowing that he will perform other prayer later at night, that is still allowed, though it is considered makruh, as was stated by the Malikis.
The reason for it being makruh is the intent (to perform the later prayers) even before starting the witr (knowing that witr should be performed last).
