Imam as-Sadiq (a) said: “The last servant who will be sent to Hell will turn his face towards Allah. The Lord then will order the angels to bring him back. ‘Why did you turn your face, servant?’ the Lord will ask. ‘Lord,’ the servant will say, ‘I had another idea about You.’ ‘What did you think of Me, servant?’ the Lord will ask. The servant will answer, ‘I thought You would forgive me and allow me to live in Your Paradise.’ The Lord then will say, ‘My angels, I swear by My power, majesty, favors, tests , and exaltation, this servant had never thought good about Me for a single hour of his lifetime. Had he done so, I would not have sent him to Hell. Nevertheless, I will regard the lie that he has just told as true and allow him to be in Paradise.’
Allah will live up to the servant who thinks well of Him:
‘This was how you considered your Lord, but He knows you better than you know yourselves. Thus, you are now lost (41:23).’" ( 5 )
Imam ar-Rida (a) said: “Have favorable judgment about Allah, for He says: I am as My servant thinks of Me, whether good or bad." ( 6 )
