Re: Forgive
Peace Mahool,
We have example from the life of our Prophet Muhammad 
that on many many occasions, He forgiven his enemies as well others. It is a very long subject (in my view) and hard to describe in short. However I’ll try to share my views in short.
As we aware that the angels ask forgiveness from Almighty Allah for us till we are sitting in our Musallah. Also when we say “Ameen” in prayers, and our “Ameen” coincides with the “Ameen” of Angels then our all past sins will be forgiven. It is also narrated in a hadith Book ‘The Book of Faith (Kitab Al-Iman)’ of Sahih Muslim Hadith No. 0221:
It is narrated on the authority of Ibn 'Abbas that some persons amongst the polytheist had committed a large number of murders and had excessively indulged in fornication. Then they came to Muhammad and said: Whatever you assert and whatever you call to is indeed good. But if you inform us that there is atonement of our past deeds (then we would embrace Islam). Then it was revealed: And those who call not unto another god along with Allah and slay not any soul which Allah has forbidden except in the cause of justice, nor commit fornication; and he who does this shall meet the requital of sin. Multiplied for him shall be the torment on the Day of Resurrection, and he shall therein abide disgraced, except him who repents a believes and does good deeds. Then these! for the Allah shall change their vices into virtues. Verily Allah is Ever Forgiving, Merciful (Surah Al Furqan Chapter 25 Verses 68-70). Say thou: O my bondsmen woo have committed extravagance against themselves despair not of the Mercy of Allah I Verily Allah will forgive the sins altogether. He is indeed the Forgiving, the Merciful (Sura Az Zumur Chapter 39 Verse 53).
If we read above hadith and try to understand it and then we’ll came to know that Almighty Allah is most Merciful upon us. HE is trying to create so much opportunities for us that if we avails it, we’ll be forgiven. So I think Almighty Allah likes us all and want to forgive us. If we start liking each others (as narrated in hadith that A Muslim is a brother of another Muslim) then yes we can forgive each others on mistakes and surely there would be some rewards on our deed.
