Those people who are impatient fall into the clutches of Satan. A righteous person must battle with impatience as well.
In Bustan there is mention of a worshipper. Whenever this individual stood for worship, he would a voice from the unseen saying: ‘You have been rejected and forsaken.’ On a certain occasion, one of his disciples heard this voice and said: ‘Now the verdict has been passed. What then is the use of futile action?’
The man wept profusely and said: ‘If I am to leave God, where else should I go? If accursed I am, then so be it. At least I am fortunate enough to be called accursed.’ These discussions were still underway with his disciple, when a voice was heard saying: ‘You have been accepted.’
So all this was the result of sincerity and patience, which is a condition for one who is righteous.
