Zikr

1) Zikr keeps away the Satan and weakens his strength.
2) It is the cause of Almighty Allah’s pleasure.
3) It relieves the mind of anxieties and worries.
4) It produces joy and happiness in the heart.
5) it strengthens the body and mind.
6) It brightens the face and heart.
7) It attracts one’s subsistence.
8) It induces love for Allah, which in fact is the spirit of Islam and the pivot of “Deen”, and the source of success and salvation in the Hereafter. He who seeks access to the love of Almighty Allah should do Zikr profusely. Just as reading and repetition is the door of knowledge, so Zikr of Allah is the gateway to His love.
9) Zikr of Allah causes one’s mention in the Court of Allah, as said in the Holy Book.
(Remember Me, and I will remember you), and as stated in the Hadith (whosoever remembers Me in his heart, I remember him in My heart). It has already been explained under other verses and Ahadith that, even if there were no other good points in Zikr, except that mentioned above, this alone would have established its superiority over others. Nevertheless, there are many more virtues and benefits of Zikr.
10) It helps realization of Allah so that by and by a stage is reached when he comes to regard Almighty Allah as his sole Cherisher, Guardian and Master, and he turns unto Him, in all afflictions.
11) It is the key to nearness to Almighty Allah; the greater the Zikr, the greater the nearness to Allah, and greater the indifference to Zikr, the greater the distance from him.
12) It gives life to the heart. Hafiz Ibn Tamimia says that Zikr is as necessary for the heart as water for the fish. Imagine the condition of a fish out of water.
