Some believe that Wajib prayers are compulsory while there are those who believe that since the 5 prayers are obligatory, it automatically renders all other prayers optional.

• Witr – Witr is performed after the salah of isha’a (dusk). Some Muslims consider witr wajib while others consider it optional. It may contain any odd number of raka’ah from one to eleven according to the different schools of jurisprudence. However, Witr is most commonly offered with three raka’ah.
• Eid – Eid Salah is performed on the morning of Eid ul-Fitr and Eid ul-Adha. It consists of two raka’at, with seven takbirs offered before the start of the first raka’ah and five before the second. After the Salah is completed, a sermon (khutbah) is offered. However, the khutbah is not an integral part of the Eid Salah. The Eid Salah must be offered between sunrise and true noon i.e. between the time periods for Fajr and Zohr.
