A Peep into Allah's Writ.

As-Salaam alaikum,
  The Noble Prophet, Sallallahu alaihi Wasallam, said:--

   ''When Allah created creation, He inscribed in His Writ that He
    has made binding on Himself, it being reposited nigh to Him upon
    the very Throne: 'Verily My Mercy surpasses My Wrath.''
                                        (Bukhari (2), 9.147: 7404.s)

 From this, we understand that there is Divine Mercy and there is Divine Wrath, the former being of Allah's infinite beauty (Jamal), the latter of His limitless Majesty (Jalal) and Justice. He says, in the Holy Qur'an:--

    "My chastisement I but smite with whom I will, while My Mercy
   encompasses everything: I shall inscribe it for those who show
   Godfearingness, and pay the alms, and who in Our revealed signs
  are wholehearted believers.'' (7:156)


 That is, His Mercy is prescribed for those willing to listen and follow. May we be made among those who listen and follow, ameen..
Best Wishes.
