Remember Allah, The Best of Worship

Our heart is without any doubt unclean and rusted and there is no other means of purifying it than performing Zikr of Allah, as mentioned in the above Hadith. Surely, Zikr purifies our hearts and makes it shine like a perfectly polished mirror. When one leaves Zikr, lethargy and sins engulf him . The heart can be polished by Istighfar {Seeking forgiveness of Allah Almighty  } and by doing Zikr. Those who live in lethargy will have their heart covered with layers of rust. Whilst the clean purified heart will reflect faithfully the reality as it is in fact, the heart filled with filth would reflect deformed truth in such a confused way that truth would become falsehood and vice-verse. And this is the worst punishment that can be inflicted on the heart. The sole reason for this state of the heart is the ignorance for the need of Zikr since this ignorance destroys the light of heart. Allah Almighty  says in the Holy Quran:
“And keep yourself familiar to those who call upon their Lord in the morning and evening seeking His pleasure and your eyes should not see others leaving them; would you like the adornment of the life of this world? and obey not him whose heart We have made neglectful of Our rememberence and who followed his own desires and whose affair exceeded the limit.” {Al Kahf; 18: 28}
This is why all the Spiritual Guides strongly advise the Salihin {Righteous} to perform as much Zikr as possible and teach them that Zikr is the practical means to become close to Allah Almighty  . The Spiritual Guides also encourage the Salihin to have a close contact with the Zakirin since the breath of the latter destroys their desires {An Nafs al Ammarat bis Soo’e} and their violent impulses.
