The Heart Is Amazing.

As-Salaam alaikum,

Says Allah, Jallah-Jalalahu, in Surat Ra'ad of the Holy Qur'an:--

  "VERILY, IN THE REMEMBRANCE OF ALLAH DO HEARTS
   FIND REST/SATISFACTION." (13:28)

And in the Hadith, the Noble Messenger of Allah, Sallallahu alaihi Wasallam, was quoted saying:--

 "There is a piece of flesh in the body, if it becomes good
  (reformed), the whole body becomes good but if it gets
 spoiled, the whole body gets spoiled and that is the heart."

Imam Abu Abdullah at-Tirmidhi Hakeem, may Allah be Merciful to him, said that "The Zikr [remembrance] of Allah moistens the heart and cultivates tenderness in it. When the heart is bereft of Zikrullah, the heat of the nafs (ego) overtakes it; the fire of lust reaches it and it becomes barren and hard."

Indeed, the life of the heart (qalb) is related to Allah's Remembrance. Man has only to implant Allah's Name firmly in his heart, and what follows is amazing. So, be always or most of the time(s) engaged in Zikr..  With that you find out that even though our hands cannot feel Allah Ta'ala, the mind cannot grasp Him but the heart would vividly recognize Him.

With regular, constant Zikr, the heart can discern Allah Ta'ala, hear Him, entreat, obey and act according to His Will, Tabaraka Wa Ta'ala.
