﴿وَلَقَدْ أَرَيْنَـهُ ءَايَـتِنَا كُلَّهَا فَكَذَّبَ وَأَبَى ﴾

(And indeed We showed him (Fir`awn) all Our Ayat, but he denied and refused.) This means that the proofs, signs and evi- dences were establi- shed against Fir`awn and he saw them with his own eyes, but he still denied and rejec- ted them due to his disbelief, abstinence and transgression. This is as Allah, the Exalted, says,

﴿وَجَحَدُواْ بِهَا وَاسْتَيْقَنَتْهَآ أَنفُسُهُمْ ظُلْماً وَعُلُوّاً﴾

(And they belied them wrongfully and arrogantly, though they themselves were convinced thereof.) ﴿27:14﴾

﴿قَالَ أَجِئْتَنَا لِتُخْرِجَنَا مِنْ أَرْضِنَا بِسِحْرِكَ يمُوسَى - فَلَنَأْتِيَنَّكَ بِسِحْرٍ مِّثْلِهِ فَاجْعَلْ بَيْنَنَا وَبَيْنَكَ مَوْعِداً لاَّ نُخْلِفُهُ نَحْنُ وَلاَ أَنتَ مَكَاناً سُوًى - قَالَ مَوْعِدُكُمْ يَوْمُ الزِّينَةِ وَأَن يُحْشَرَ النَّاسُ ضُحًى ﴾

(57. He (Fir`awn) said: "Have you come to drive us out of our land with your magic, O Musa'') (58. "Then verily, we can produce magic the like thereof; so appoint a meeting between us and you, which neither we nor you shall fail to keep, in an open place where both shall have a just and equal chance.'') (59. (Musa) said: "Your appointed meeting is the day of the festival, and let the people assemble when the sun has risen (forenoon).'')
