Shaykh Wasiullah (Allah have mercy on him) said,

‘The effect of real acts of obedience is that an individual does not observe any virtue (kamal) in him/herself at all.

If there in no development of  humility, abasement, feeling of inability and lowliness after an act of worship then one should consider that this worship lacked sincerity.’

‘Iteraf e zunoob, page 99

The reason is that true worship illuminates the inner-self which in turn reveals the actual state within.

For example, it is like switching on the light bulb in a dark room. The illumination will reveal all the defects that were concealed by the darkness.

Cognizant of all the deficiencies an individual is now better equipped for attempting their rectification.

Similar should be our condition after Ramadhan.
