The Merciful Lord Almighty
Almighty Allah is most merciful on His creation. In the beginning of the Holy Quran when Almighty Allah introduces Himself, He did so with 3 of His attributes:
الْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَO. الرَّحْمَنِ الرَّحِيمِO
All praise be to Allah alone, the Sustainer of all the worlds. Most Compassionate, Ever-Merciful, [1]
Surah Fatiha which is like a foreword to the Holy Quran has a mention of these 3 attributes. All these 3 attributes show the mercy and benevolence of Almighty Allah. All the rules of Islam are but detailed explanations and interpretations of Surah Fatiha and will have the attribute of mercy in them as a predominant factor. Why not? The mercy of Allah is for each and every person, for every strip of land and for every thing in this world as the Merciful Lord says:
وَرَحْمَتِي وَسِعَتْ كُلَّ شَيْءٍ
My mercy encompasses everything.[2]
