This trait is against mankind which is full of lies and selfishness. God gives a clear explanation of Himself in holy books such as the Holy Quran and the Holy Bible. God is full of accuracy in what He says and does. We can welcome God's promises. He promised this in the sacred books. "The revelation of your words illuminates, gives intelligence to the simple. Your word is a lamp to my step, a light on my path". (Psalms 119:130,105) this is explained in the Holy Bible. In the Quran, He also stated the following: “And it is He who created you generation after generation, replacing each other on earth. And He has elevated you in rank – some above others – so that He can test you in what He has bestowed upon you. Surely your Lord is swift in punishment, and He is certainly often* forgiving, merciful.” (Sura al-An'am
