Here I come just like a newborn babies...

ما من عبد يذنب ذنبا فيحسن الطهور , ثم يقوم فيصلي ركعتين , ثم يستغفر الله إلا غفر الله له

There is not any slave of Allah who commits a sin, then he perfects his ablution and stands to pray two rak'ah of prayer, then seeks Allah's forgiveness, except that Allah will forgive him.

Abu Dawud 2/86 , At-Tirmizi 2/257
