﴿ 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 ﴾

“And so, [in the course of time,] We awakened them; and they began to ask one another [as to what had happened to them]. One of them asked: "How long have you remained thus?" [The others] answered: "We have remained thus a day, or part of a day." Said they [who were endowed with deeper insight]: "Your Sustainer knows best how long you have thus remained. Let, then, one of you go with these silver coins to the town, and let him find out what food is purest there, and bring you thereof [some] provisions. But let him behave with great care and by no means make anyone aware of you:”

And so just as We did with them that which We have mentioned it was that We aroused them We awakened them that they might question one another concerning their state and the length of their stay in the cave. One of them said ‘How long have you tarried?’ They said ‘We have tarried a day or part of a day’ he said this because they had entered the cave at sunrise and were awakened at sunset and so they thought that it was the time of sunset on the day of their entry. Then they said unsure about this fact ‘Your Lord knows best how long you have tarried. Now send one of you with this silver coin of yours read bi-warqikum or bi-wariqikum to the city — which is said to be the one now called Tarsus Tarasūs — and let him see which is the purest food that is which of the foods of the city is the purest and let him bring you a supply thereof. Let him be careful and not make anyone aware of you.
