Sunnah Prayers
Sunnah prayer (Arabic: صلاة السنة) is an optional or supererogatory salah (ritual prayer) that can be performed in addition to the five daily salah, which are compulsory for all Muslims. Sunnah prayer have different characteristics: some are done at the same time as the five daily compulsory prayers, some are done only at certain times (e.g. late at night), or only for specific occasions (e.g. during a drought); some have their own name (e.g. Tahajjud) and some are identified by how they are performed (e.g. "4 (rakat) before Zuhr and 2 after"). The length of Sunnah prayer also varies.
While the five daily salah are wajib/fard (obligatory), Sunnah prayer (and other sunnah deeds) are Mustahabb (encouraged) -- those who perform them will earn a reward in the afterlife, but there will be no punishment for neglecting them.
Sunnah of Wuhdu (ablution)
Tahajjud, also known as the "night prayer", is a voluntary prayer performed by followers of Islam. It is not one of the five obligatory prayers required of all Muslims, although the Islamic prophet, Muhammad was recorded as performing the tahajjud prayer regularly himself and encouraging his companions too.
