Allah is The Most Merciful, The Most Compassionate. We are been ordered to recite and repeat these names of Mercy at least forty times in our daily obligatory Prayers ( Sura Al-Hamd contains four times of remembering the Mercy of Allah in Arrahmaan Arraheem, and it it must to recite Al-Hamd at least two times in the first and second Rak'ats in each of the five obligatory daily Prayers)

Allah The Most Merciful never punishes His creatures whom He created to shower on them His Mercy. Allah's Mercy is much greater than our imaginations. All of us are overwhelmed by His Mercy in every moment. Enemies of Allah are those who damage the life of others and insist on their crimes ignoring and rejecting Allah's continuous invitations to them to repent and leave their criminal behaviour, will be entitled to be punished. Punishment for such enemies of humanity is mentioned in Quran and Hadeeth. Eternal torment is the result of their evil intention to continue committing the crimes against humanity as far as they can. We don't know the limits of the Mercy of Allah and how He will deal with them. What we know for sure is Allah is the source of Mercy and does not punish but only those who are the worst enemies of humanity who committed worst crimes and insisted and remained criminals till death and had the intention to go on in their evil acts.

Wassalam.
