Yusuf - 12:82

وَاسْأَلِ الْقَرْيَةَ الَّتِي كُنَّا فِيهَا وَالْعِيْرَ الَّتِي أَقْبَلْنَا فِيهَا وَإِنَّا لَصَادِقُونَ
[12:82]
And inquire in the town in which we were and the caravan with which we proceeded, and most surely we are truthful.
"'Ask at the town where we have been and the caravan in which we returned, and (you will find) we are indeed telling the truth.'"
Ask the township where we were, and the caravan with which we travelled hither. Lo! we speak the truth.
