Surah 10. Yunus
Ayah 94 - 97
94 فَإِن كُنتَ فِى شَكٍّ مِّمَّآ أَنزَلْنَآ إِلَيْكَ فَسْـَٔلِ ٱلَّذِينَ يَقْرَءُونَ ٱلْكِتَـٰبَ مِن قَبْلِكَ ۚ لَقَدْ جَآءَكَ ٱلْحَقُّ مِن رَّبِّكَ فَلَا تَكُونَنَّ مِنَ ٱلْمُمْتَرِينَ
95 وَلَا تَكُونَنَّ مِنَ ٱلَّذِينَ كَذَّبُوا۟ بِـَٔايَـٰتِ ٱللَّهِ فَتَكُونَ مِنَ ٱلْخَـٰسِرِينَ
96 إِنَّ ٱلَّذِينَ حَقَّتْ عَلَيْهِمْ كَلِمَتُ رَبِّكَ لَا يُؤْمِنُونَ
97 وَلَوْ جَآءَتْهُمْ كُلُّ ءَايَةٍ حَتَّىٰ يَرَوُا۟ ٱلْعَذَابَ ٱلْأَلِيمَ
94. So if you are in doubt concerning that which We have revealed unto you, then ask those who are reading the Book before you. Verily, the truth has come to you from your Lord. So be not of those who doubt (it). 95. And be not one of those who belie the Ayat of Allah, for then you shall be one of the losers. 96. Truly, those, against whom the Word of your Lord has been justified, will not believe. 97. Even if every sign should come to them, until they see the painful torment.
Allah said:
(Those who follow the Messenger, the Prophet who can neither read nor write whom they find written of with them in the Tawrah and the Injil.)(7:157) They are as certain of this as they are about who their children are, yet they hide it and distort it. They did not believe in it despite its clear evidence. Therefore Allah said:
(Truly, those, against whom the Word (wrath) of your Lord has been justified, will not believe. Even if every sign should come to them, until they see the painful torment.) meaning they would not believe in a way that they might benefit from that belief. This is when they believe at a time one may not be able to benefit from his belief. An example is when Musa prayed against Fir`awn and his chiefs, saying:
(Our Lord! Destroy their wealth, and harden their hearts, so that they will not believe until they see the painful torment.)(10:88) And Allah said:
(And even if We had sent down unto them angels, and the dead had spoken unto them, and We had gathered together all things before their very eyes, they would not have believed, unless Allah willed, but most of them behave ignorantly.) (6:111) Allah then said:
