Remembrance of God is entrusted to seven parts in the body

7-115 There are seven parts of the body entrusted with remembrance of God: the tongue, the soul, the spirit, the intellect, the wisdom, the head, and the heart one of which needs to persevere. The tongue’s perseverance is attained through honesty in uttering words. The soul’s perseverance is attained through presence of one’s mind. The spirit’s perseverance is attained through sincerity in repentance. The heart’s perseverance is attained through properly begging for pardon. The intellect’s perseverance is attained through properly learning from one’s mistakes. The wisdom’s perseverance is attained through proper pride, and the head’s perseverance is attained through awareness of the secrets of the world. Thus, the remembrance of God is equal to uttering praises of God for the tongue; struggling and hard work for the spirit; fear and hope for the soul; honesty and sincerity for the heart; exaltation and shyness for the intellect; submission and contentment for the wisdom; and witnessing to and approaching God for the head."This has been narrated by Abu Muhammad ibn Abdullah ibn Hamid who has linked it up to some of the good-doers - may God bless them.
