SHAFAQNA (Shia International News Association) – The first degree of submission to the will of Allah (SWT) is that the believer refrains from expressing dissatisfaction and do not show weakness against bitter events which may happen in life for a person. The second degree is the submission of knowledge to circumstance, submission of intention to discovery, submission of custom to truth. When a believer reaches from knowledge to wisdom and from wisdom to circumstance, cannot return to the past.
The third degree is the submission of inferior truth to the truth, noting that reaching the position of submission is a special favour from Allah (SWT) to the believer and through this noble position the believer reaches the truth and sees that all the existence are under the rule of the Almighty. Meaning through witnessing, they will understand that there is nothing in the sky or on the earth unless they are the obedient servants of Allah (SWT) .
