All the activities and rituals being done by Muslims across the globe are all based on what Sunnah has set which they believed are rules given by their beloved Prophet Muhammad.
Some of the things that they do at the start of the first day of the celebration is for them to wake-up early in the morning and the closing of the dawn offer a prayer called Salat ul-Fajr.
Prior to their attendance to special congregations where Salaat al-Eid prayer will be done, they have to do the basic hygiene and they have to put on perfume to their body.
Included on this are their charitable works, recitation of takbir and other things which are in harmony on what can be read on Sunnah.
