quran:33:22 –

And when the believers saw the companies, they said, "This is what Allah and His Messenger had promised us, and Allah and His Messenger spoke the truth." And it increased them only in faith and acceptance.  

And when the believers saw the confederates, of disbelievers, they said, ‘This is what God and His Messenger promised us, in the way of trial and ˹assistance to˺ victory, and God and His Messenger were truthful’, about the promise. And that only increased them in faith, in belief in God’s promise, and submission, to His command.
القرآن:٣٣:٢٢ –

وَلَمَّا رَأَى الْمُؤْمِنُونَ الْأَحْزَابَ قَالُوا هَٰذَا مَا وَعَدَنَا اللَّهُ وَرَسُولُهُ وَصَدَقَ اللَّهُ وَرَسُولُهُ ۚ وَمَا زَادَهُمْ إِلَّا إِيمَانًا وَتَسْلِيمًا  

{ولمَّا رأى المؤمنون الأحزاب} من الكفار {قالوا هذا ما وعدنا الله ورسوله} من الابتلاء والنصر {وصدق الله ورسوله} في الوعد {وما زادهم} ذلك {إلا إيمانا} تصديقا بوعد الله {وتسليما} لأمره.
