﴿ لَّوْ مَا تَأْتِينَا بِٱلْمَلَٰٓئِكَةِ إِن كُنتَ مِنَ ٱلصَّٰدِقِينَ ﴾

“Why dost thou not bring before us angels, if thou art a man of truth?”

(Why bringest thou not angels unto Us) from heaven so that they bear witness that you are Allah's Messenger, (if thou art of the truthful?) in what you say.
