We have sent you an Apostle from amongst you to convey to you Our Revelations and to purify you...

Holy Qur'an, al-Baqarah, 151

"The likeness of the one who remembers his Lord and the one who does not remember his Lord is that of the living and the dead."

Master Prophet Muhammad (pbuh); Al-Bukhari

"Every organ of our bodies performs a particular function. If it fails to perform its function or performs with nuisance or anguish, then it would be considered unhealthy. Similarly, an unhealthy (spiritual) heart is not capable to perform its specific function - recognising and realising God Almighty. It would only regain its health through purification while acquiring constant awareness of Allah (God) resulting in knowing Him and the rising of love and (humanly) perfect worship of Allah."

Sayid Abulharith Abdullah Al-Hasani Al-Madani
