Surah Al-Kahf, Verse 19
وَكَذَٰلِكَ بَعَثْنَٰهُمْ لِيَتَسَآءَلُوا۟ بَيْنَهُمْ ۚ قَالَ قَآئِلٌۭ مِّنْهُمْ كَمْ لَبِثْتُمْ ۖ قَالُوا۟ لَبِثْنَا يَوْمًا أَوْ بَعْضَ يَوْمٍۢ ۚ قَالُوا۟ رَبُّكُمْ أَعْلَمُ بِمَا لَبِثْتُمْ فَٱبْعَثُوٓا۟ أَحَدَكُم بِوَرِقِكُمْ هَٰذِهِۦٓ إِلَى ٱلْمَدِينَةِ فَلْيَنظُرْ أَيُّهَآ أَزْكَىٰ طَعَامًۭا فَلْيَأْتِكُم بِرِزْقٍۢ مِّنْهُ وَلْيَتَلَطَّفْ وَلَا يُشْعِرَنَّ بِكُمْ أَحَدًا
Translation — Sahih International
And similarly, We awakened them that they might question one another. Said a speaker from among them, "How long have you remained [here]?" They said, "We have remained a day or part of a day." They said, "Your Lord is most knowing of how long you remained. So send one of you with this silver coin of yours to the city and let him look to which is the best of food and bring you provision from it and let him be cautious. And let no one be aware of you.
