حَتَّىٰٓ إِذَا ٱسۡتَيۡـَٔسَ ٱلرُّسُلُ وَظَنُّوٓاْ أَنَّهُمۡ قَدۡ كُذِبُواْ جَآءَهُمۡ نَصۡرُنَا فَنُجِّيَ مَن نَّشَآءُۖ وَلَا يُرَدُّ بَأۡسُنَا عَنِ ٱلۡقَوۡمِ ٱلۡمُجۡرِمِينَ ١١٠
[They continued] until, when the messengers despaired and were certain that they had been denied, there came to them Our victory, and whoever We willed was saved. And Our punishment cannot be repelled from the people who are criminals.
Translation: Saheeh International (English)
Each word's meaning and sound
Allah gave time to the enemies of these messengers He sent, not being quick to punish, but luring them gradually until when their destruction was overdue, and the messengers despaired of it and the disbelievers thought that their messengers had lied to them in their promises of a punishment for those who deny the truth and the rescue of those who have faith; then Allah’s help came to His messengers, saving the messengers and believers from the destruction which the disbelievers suffered, and Allah’s punishment cannot be turned away from the sinners when He sends it down.
