As it is said ‘to err is human’, we are liable to indulge in sins and make mistakes throughout our daily routines of life. We are aware of some of these sins and mistakes but we find it hard to avoid them. There are also some mistakes and sins which we commit and of which we are not aware.
Another fact is that the good acts we perform are nullified by some kinds of sins and mistakes which we make. Therefore, the only way to save our good deeds is to ask Allah for forgiveness.
