The word Tawbah (Repentance) in Arabic literally means 'to return'. In an Islamic context, it refers to the act of leaving what Allaah has prohibited and returning to what He has commanded.The subject of repentance is one which concerns all people who believe in God, and is vital one for the Muslims to understand because our salvation in the hereafter is dependent on our repentance to Allah.
Allah Says:
وَتُوبُوا إِلَى اللَّهِ جَمِيعًا أَيُّهَا الْمُؤْمِنُونَ لَعَلَّكُمْ تُفْلِحُونَ
And repent to Allah O believers, all of you, so that you may achieve success.
[24:31]
يَا أَيُّهَا الَّذِينَ آمَنُوا تُوبُو
He says, "O you who believe! Turn in sincere repentance to Allah."
[66:8]
وَتُوبُوا إِلَى اللَّهِ جَمِيعًا أَيُّهَا الْمُؤْمِنُونَ لَعَلَّكُمْ تُفْلِحُونَ
Surely Allah loves those who are most repenting, and loves those who keep themselves pure.
[2:222]
Freedom lies in submission to your Creator. Otherwise we are chained to our desires and to the false hopes that this world offers us.
