He gets afflicted by heedlessness and self-admiration.
Even if he were to content himself with saying one ‘Praise be to Allah’, he still has not discharged the right of thanking Allah for it because just saying ‘Praise be to Allah’ is a grace and favor that Allah has granted unto him, and itself stands in need of thanksgiving. Therefore, for every thanksgiving, there is [yet] another incumbent thanksgiving.
That is to say, if we were to [repeatedly] say ‘Thanks be to Allah’ up to the Day of Resurrection, we still would not have discharged the right of one ‘Praise be to Allah’, therefore, how can we be able to fulfill the rights of all these graces which creatures are not able to count?
Attention to this point that the graces of Allah are uncountable and He has a lot of rights upon man inspires a feeling of modesty and humility in man who still feels indebted to Allah even if he has not perpetrated any sin. Therefore, if man cannot fulfill all the thanksgiving for Allah’s graces and discharge His rights, the greatest work he can do is to preserve the condition of repentance and quitting the small sins, humble submissiveness to Allah and acknowledging sin and dereliction of duty.
This in itself withholds man from pride and delusion, because when man gets deviated from the correct path, he gets stricken by materialism, complacency and self-indulgence, and when he gets guided to the correct path and performance of duties for the first time, he gets afflicted by pride and egotism.
He compares himself with the others and tells himself that people do not know the value of Allah’s favors and are contaminated by sin, but we have been successful at discharging [divine] duties and appreciating blessings! Therefore, despite that we ought to be responsible and practical people with regard to our duties, we ought not to be stricken by pride; this is the greatest lesson of edification of character that can be deduced from the words of the ( ‘a ).
