Parallel with the degrees of certainty, there exist different effects and signs for it. Those who are at the stage of Haqq al-Yaqin enjoy a better degree of recognition and high temperaments. They can perform extraordinary feats. They who live at the other two degrees of certainty (i.e.) ‘Ilm al-Yaqin and ‘Ayn al-yaqin, naturally enjoy fewer advantages.
The writer of “Misbah al-Shari’ah” writes, Imam Sadiq (as) has said: “Certainty raises the status of the man to a lofty one, and the Great Prophet of Islam (S), hearing that Jesus Christ (as) had walked over water, replied: ‘If Jesus enjoyed greater certainty, he would have walked on air as well’”.
This statement depicts the lofty degree of certainty.
All Prophets are not on the same footing. Some who have more certainty are of higher status.
As the Prophets enjoy different degrees of certainty, so do the believers. A man who enjoys a better degree of certainty, naturally sees power and might only in the hands of Allah and insists on worshipping Him both publicly and in private. Existence or lack of it, more or less, appreciation or depreciation, glory or abjectness is equal for him…."6
