In Surah al-Waaqi`ah, Allaah says: أَفَرَأَيْتُمُ الْمَاءَ الَّذِي تَشْرَبُونَ * أَأَنتُمْ أَنزَلْتُمُوهُ مِنَ الْمُزْنِ أَمْ نَحْنُ الْمُنزِلُونَ * لَوْ نَشَاءُ جَعَلْنَاهُ أُجَاجًا فَلَوْلَا تَشْكُرُونَ {And have you seen the water that you drink? Is it you who brought it down from the clouds, or are We the Causer of it to come down? If We willed, We could make it bitter, so why are you not grateful?} [Surah al-Waaqi`ah (56): 68-70] أَفَرَءَيْتُمُ الْمَآءَ الَّذِى تَشْرَبُونَ أَءَنتُمْ أَنزَلْتُمُوهُ مِنَ الْمُزْنِ {Do you not see the water that you drink? Is it you who cause it to come down from Al-Muzn?} Al-Muzn meaning clouds, according to Ibn `Abbas, Mujahid and others. Allaah تعالى said: أَمْ نَحْنُ الْمُنزِلُونَ {or are We the Causer of it to come down?} Allaah is stating that indeed He alone is the One Who causes the rain to fall, لَوْ نَشَآءُ جَعَلْنَـهُ أُجَاجاً {If We willed, We verily could make it salty;} Meaning salty, sour, undrinkable and unfit for growing plants, فَلَوْلاَ تَشْكُرُونَ {why then do you not give thanks} `why do you not appreciate the favor Allaah does for you by sending down the rain fresh, ready to consume,' هُوَ الَّذِى أَنْزَلَ مِنَ السَّمَاءِ مَآءً لَّكُم مَّنْهُ شَرَابٌ وَمِنْهُ شَجَرٌ فِيهِ تُسِيمُونَ - يُنبِتُ لَكُمْ بِهِ الزَّرْعَ وَالزَّيْتُونَ وَالنَّخِيلَ وَالأَعْنَـبَ وَمِن كُلِّ الثَّمَرَتِ إِنَّ فِى ذَلِكَ لآيَةً لِّقَوْمٍ يَتَفَكَّرُونَ {From it you drink and from it (grows) the vegetation on which you send your cattle to pasture. With it He causes to grow for you the crops, the olives, the date palms, the grapes, and every kind of fruit. Verily, in this is indeed an evident proof and a manifest sign for people who give thought.} [Surah al-Nahl (16): 10-11] #Tafseer_Ibn_Katheer,#quran,#wordsofallah,#faveayat
