There is a stark difference between how Sunni Muslims perform Ramadan rituals and how Shia Muslims do. Sunni Muslims attempt to recite the whole Quran at one go via special eid ul fitr prayer ceremony, which they have named as 'Tarawih'. This goes on during the entire month of Ramadan.
Whereas, Shia Muslims call the same practice as 'Bidah' and beware all not to perform it. Rather, they perform 'Qiyam-al-layl' or 'Tahajjud' at every night of the month.
The holy month of Ramadan is divided into three parts:Rahmat, Maghfirat and Nijat. While Rahmat means "mercy of God, Maghfirat means "forgiveness of God" and Nijat means "salvation". As their meaning suggest, Muslims (followers of the holy Quran), ask for Allah's blessings to make their life meaningful. There in lies the significance of Ramadan.
Ramadan is the period of purgation after which heaven is met. Ramadan ends with Eid-Ul-Fitr, which is one of the most celebrated festivals of Muslims across the world. Celebrate Ramadan in a healthy way while you ask for happiness for yourself and your loved ones.
