Amal

Amal is carried out through intention but action can be intentional or unintentional, Amal transcends the limbs and reaches the heart, as in the case of Rabiah Basriyyah (RA.). When she went on a pilgrimage to the Ka'aba Shareef, then the special blessings of Allah that perpetually descend upon the Ka'aba, were focussed on Rabiah Basriyyah (R.A.), as if they were welcoming her. Meanwhile
Hazrat Ibrahim ibnê-Adham (RA.) was proceeding to the Ka'aba performing Nafl at every step. When he reached it, he noticed the spiritual effects of the Ka'aba absent. They were at that time focussed on Hazrat Rabiah Basriyyah (R.A.). He addressed her “Just what is all the excitement you have aroused?” She said, “Have I drawn the attention of creation or have you, through your performance of Nafl at every step?” Hazrat lbrahim-ibn-e Adham (R.A.) said, “Even though I behave in the most arduous manner, yet the Ka'aba came forward to welcome you.” She said, “You came offering your head and submission and I, my heart”
