Surah Al-An'am (The Cattle), Verse 111

وَلَوْ اَنَّنَا نَزَّلْنَاۤ اِلَیْهِمُ الْمَلٰٓىِٕكَةَ وَكَلَّمَهُمُ الْمَوْتٰی وَحَشَرْنَا عَلَیْهِمْ كُلَّ شَیْءٍ قُبُلًا مَّا كَانُوْا لِیُؤْمِنُوْۤا اِلَّاۤ اَنْ یَّشَآءَ اللّٰهُ وَلٰكِنَّ اَكْثَرَهُمْ یَجْهَلُوْنَ ۟

Wa law annanaa nazzal naaa ilaihimul malaaa'ikata wa kallamahumul mawtaa wa hasharnaa 'alaihim kulla shai'in qubulam maa kaanoo liyu'minooo illaaa ai yashaaa'al laahu wa laakinna aksarahum yajhaloon

“Even if We did send unto them angels, and the dead did speak unto them, and We gathered together all things before their very eyes, they are not the ones to believe, unless it is in Allah's plan. But most of them ignore (the truth).”
