(Du'a'). Du'a is the private and personal supplication of the slave to his Lord. "Your Lord has said Call upon Me and I will answer you" (The Qur'an 2:260). "Call upon Allah, or call upon Rahman (the Merciful), By whatever name ye call upon Him, (it is well) for to Him belong the Most Beautiful Names" (The Qur'an 17:110). This personal form of prayer gives to the worshipper the opportunity to pour out his heart, expressing his longings, his fears, and his intense need of his Lord. In so doing man can rid himself of accumulated poisons and emotional debris which block the celestial channel between himself and Allah Almighty. Sitting, with head bowed and palms upturned in an attitude of readiness to receive the barakah from above, man may become a symbol, not only of spiritual poverty but also one of supreme trust.
