Sura al-Anʿām 6:34

وَلَقَدْ كُذِّبَتْ رُسُلٌ مِّن قَبْلِكَ فَصَبَرُوا۟ عَلَىٰ مَا كُذِّبُوا۟ وَأُوذُوا۟ حَتَّىٰٓ أَتَىٰهُمْ نَصْرُنَا وَلَا مُبَدِّلَ لِكَلِمَٰتِ ٱللَّـهِ وَلَقَدْ جَآءَكَ مِن نَّبَإِى۟ ٱلْمُرْسَلِينَ

wa-la-qad kudhdhibat rusulun min qablika fa-ṣabarū ʿalā mā kudhdhibū wa-ūdhū ḥatta atāhum naṣrunā wa-lā mubaddila li-kalimāti allāhi wa-la-qad jāʾaka min nabaʾi l-mursalīna

Rejected were the messengers before thee: with patience and constancy they bore their rejection and their wrongs, until Our aid did reach them: there is none that can alter the words (and decrees) of Allah. Already hast thou received some account of those messengers.

Sura Yūsuf 12:110

حَتَّىٰٓ إِذَا ٱسْتَيْـَٔسَ ٱلرُّسُلُ وَظَنُّوٓا۟ أَنَّهُمْ قَدْ كُذِبُوا۟ جَآءَهُمْ نَصْرُنَا فَنُجِّىَ مَن نَّشَآءُ وَلَا يُرَدُّ بَأْسُنَا عَنِ ٱلْقَوْمِ ٱلْمُجْرِمِينَ

ḥatta idhā istayʾasa l-rusulu wa-ẓannū annahum qad kudhibū jāʾahum naṣrunā fa-nujjiya man nashāʾu wa-lā yuraddu baʾsunā ʿani l-qawmi l-mujrimīna

(Respite will be granted) until, when the messengers give up hope (of their people) and (come to) think that they were treated as liars, there reaches them Our help, and those whom We will are delivered into safety. But never will be warded off our punishment from those who are in sin.
