The Different Types of Sousna Prayers

The sunan can be divided into two categories the first is witar which is a separate prayer and the second are the sunan linked to the five daily salawats. The Prophet sallam said whoever prays for the sake of Allah 10 rakaz a day Allah will build for him a palace in jannah or 12 rakaz per day then he'll build for him. So because of this the henafees have a different distinction i'm wondering here let me get back here the correct position witar is not wajib but it is something that the process has never left in his life even when he was even and he was traveling right.
