What is mercy of Allah?. The biggest mercy of Allah on you if he will give you the knowledge of his book. We all our life consider different things as Allah mercy like wealth, health, childern, power etc but the actual mercy of Allah is if He will give you the knowledge of his book and wisdom to understand it. If Allah will tell us the words as he told them to Adam then we will be merciful. How we will learn those words for this you will need to read the Holy Quran first:
" Then Adam recieved (some) words from his Lord, so He turned to him mercifully; surely He is oft-returning (to mercy) the Merciful."
(Para No:1 & Verse No: 37)
If you and me want the same mercy from Allah then we must follow the path given in the Holy Book. Their is only one straight path to Allah and no other ways are going towards him. We need to find and move on that path.
