Although in this video the general concept of sunnah is explored but we need to understand another very important aspect of sunnah which is the sunnah prayers. Many of us ignore the sunnah prayers simply because they're not obligatory even though there are some scholars who believe that neglecting sunnah prayers is haram. Despite this, sunnah prayers are full of rewards and we as Muslims should strive to gain the most rewards. All the 12 rakat of sunnah prayers probably won't even take more than half an hour of our time, Allah (SWT) gives us 24hrs, shouldn't we give back a portion of that time.

[Umm Habibah (radiallahu anha) reported: I heard the Messenger of Allah (salallahu alayhi wa salam) saying, "A house will be built in Jannah for every Muslim who offers twelve Rak`ah of optional Salat other than the obligatory Salat in a day and a night (to seek the Pleasure of Allah).''
