Preference of some food from other foods

وَفِى ٱلْأَرْضِ قِطَعٌۭ مُّتَجَٰوِرَٰتٌۭ وَجَنَّٰتٌۭ مِّنْ أَعْنَٰبٍۢ وَزَرْعٌۭ وَنَخِيلٌۭ صِنْوَانٌۭ وَغَيْرُ صِنْوَانٍۢ يُسْقَىٰ بِمَآءٍۢ وَٰحِدٍۢ وَنُفَضِّلُ بَعْضَهَا عَلَىٰ بَعْضٍۢ فِى ٱلْأُكُلِ ۚ إِنَّ فِى ذَٰلِكَ لَءَايَٰتٍۢ لِّقَوْمٍۢ يَعْقِلُونَ

And in the earth are tracts (diverse though) neighbouring, and gardens of vines and fields sown with corn, and palm trees - growing out of single roots or otherwise: watered with the same water, yet some of them We make more excellent than others to eat. Behold, verily in these things there are signs for those who understand!

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

Such (being their state), we raised them up (from sleep), that they might question each other. Said one of them, "How long have ye stayed (here)?" They said, "We have stayed (perhaps) a day, or part of a day." (At length) they (all) said, "Allah (alone) knows best how long ye have stayed here.... Now send ye then one of you with this money of yours to the town: let him find out which is the best food (to be had) and bring some to you, that (ye may) satisfy your hunger therewith: And let him behave with care and courtesy, and let him not inform any one about you.
