Surat Al Isra' (95-96)

{قُل لَّوْ كَانَ فِي الأَرْضِ مَلآئِكَةٌ يَمْشُونَ مُطْمَئِنِّينَ لَنَزَّلْنَا عَلَيْهِم مِّنَ السَّمَاءِ مَلَكاً رَّسُولاً} (الإسراء: 95)

95- Tell them in wisdom: If there were on earth angles who walk on earth like humans, We would have sent them a messenger from their type to understand what they say and address them, for every kind incline and likes his own kind.

{قُلْ كَفَى بِاللّهِ شَهِيداً بَيْنِي وَبَيْنَكُمْ إِنَّهُ كَانَ بِعِبَادِهِ خَبِيراً بَصِيراً} (الإسراء: 96)

96- Say to polytheists: It is enough that Allah alone would be a witness to the truthfulness of my message to you, bearing witness that I delivered it and you showed haughtiness and stubbornness. He is All-Knowledgeable of His Servant and All-Seeing of their words and actions and their causes, and He shall guide whomever He wills to the truth and leads astray who show stubbornness and refusal.
