Sura 40: AL-GHAFIR (THE FORGIVER (GOD) - Juz' 24 - Translation Qarib

فَلَمَّا جَاءَتْهُمْ رُسُلُهُمْ بِالْبَيِّنَاتِ فَرِحُوا بِمَا عِنْدَهُمْ مِنَ الْعِلْمِ وَحَاقَ بِهِمْ مَا كَانُوا بِهِ يَسْتَهْزِئُونَ ﴿۸۳﴾
When their Messengers brought them clear verses they rejoiced in such knowledge as they had; but they were encompassed by that which they mocked. (83)
فَلَمَّا رَأَوْا بَأْسَنَا قَالُوا آمَنَّا بِاللَّهِ وَحْدَهُ وَكَفَرْنَا بِمَا كُنَّا بِهِ مُشْرِكِينَ ﴿۸۴﴾
And when they saw Our Might, they said: 'We believe in Allah alone, and we disbelieve in that we used to associate with Him. ' (84)
فَلَمْ يَكُ يَنْفَعُهُمْ إِيمَانُهُمْ لَمَّا رَأَوْا بَأْسَنَا سُنَّتَ اللَّهِ الَّتِي قَدْ خَلَتْ فِي عِبَادِهِ وَخَسِرَ هُنَالِكَ الْكَافِرُونَ ﴿۸۵﴾
But when they saw Our Might their belief did not benefit them! It is the way of Allah that has passed concerning His worshipers. There, the unbelievers shall be lost. (85)
