Surah An Nahl Tafseer

يُنبِتُ لَكُم بِهِ الزَّرْعَ وَالزَّيْتُونَ وَالنَّخِيلَ وَالَاعْنَابَ وَمِن كُلِّ الثَّمَرَاتِ

With it He causes crops to grow for you, olives, date palms, grapes, and every kind of fruit.

meaning, with this one kind of water, He makes the earth sprout plants with different tastes, colors, scents and shapes.

For this reason He says,

إِنَّ فِي ذَلِكَ لايَةً لِّقَوْمٍ يَتَفَكَّرُونَ

Verily, in this there is indeed an evident proof and a manifest sign for people who give thought.

meaning, this is a sign and a proof that there is no god besides Allah, as He says:

أَمَّنْ خَلَقَ السَّمَـوَتِ وَالاٌّرْضَ وَأَنزَلَ لَكُمْ مِّنَ السَّمَأءِ مَأءً فَأَنبَتْنَا بِهِ حَدَايِقَ ذَاتَ بَهْجَةٍ مَّا كَانَ لَكُمْ أَن تُنبِتُواْ شَجَرَهَا أَإِلَـهٌ مَّعَ اللَّهِ بَلْ هُمْ قَوْمٌ يَعْدِلُونَ

Is not He (better than your gods) Who created the heavens and the earth, and sends water down for you from the sky, from which We cause wonderful gardens full of beauty and delight to grow! You are not able to cause the growth of their trees.

Is there any ilah (god) with Allah!

Nay, but they are a people who make equals (to Him)! (27:60
