(Asshuara’) 26 : 154
مَا أَنْتَ إِلَّا بَشَرٌ مِثْلُنَا فَأْتِ بِآيَةٍ إِنْ كُنْتَ مِنَ الصَّادِقِينَ

 “You are none except a man like ourselves, so you bring a Sign if you are among the truthful."

It is told in verse 54: 25: “The disbelievers ridiculed Messenger Swalih as: “Has Adhikr been sent down upon him from among us? Nay, he is an odd liar”. They will know tomorrow who is the odd liar”. See explanation 6: 37-38; 17: 59-60 and 26: 4.
