Allah ordains every soul in the Quran to Perform Zikr(Remembrance). This not only means reciting the Quran and Tasbeeh(recitals) but also Zikr-e Qalb(Remembrance of Heart). It is only through Zikr-e Qalbi(Remembrance of Heart) that Prophetic Lights reach the depths of human soul and purify it from all vice and evil. Zikr(Remembrance of Divine) infuses a realization of constant Divine Presence and a seeker feels great improvement in the level of sincerity and love towards Allah and the holy Prophet-SAWS. Such levels of sincerity, love and feelings of Divine Presence can never be obtained without Zikr(Remembrance).
It would be a mistake to believe that Zikr(Remembrance) may be a requirement only for the very pious and virtuous people. Zikr(Remembrance) provides the Prophetic blessings which are in effect the life line of every human soul. It transforms even the most corrupted humans into virtuous souls by bringing out the best in them.
The fact is that Zikr(Remembrance) is the only way to achieve true contentment and satisfaction in life. The holy Quran has pointed to this eternal fact that it is only through Zikr Allah(Rmembrance of Divine) that hearts can find satisfaction. Such satisfaction and peace are the ultimate requirements of every person, regardless of religion, race and ethnicity. Practicing Zikr(Remembrance) regularly removes all traces of anxiety and restlessness, and guides the human soul to eternal bliss and peace.
