وَهُوَ الَّذِي أَنزَلَ مِنَ السَّمَاءِ مَاءً فَأَخْرَجْنَا بِهِ نَبَاتَ كُلِّ شَيْءٍ فَأَخْرَجْنَا مِنْهُ خَضِرًا نُّخْرِجُ مِنْهُ حَبًّا مُّتَرَاكِبًا وَمِنَ النَّخْلِ مِن طَلْعِهَا قِنْوَانٌ دَانِيَةٌ وَجَنَّاتٍ مِّنْ أَعْنَابٍ وَالزَّيْتُونَ وَالرُّمَّانَ مُشْتَبِهًا وَغَيْرَ مُتَشَابِهٍ انظُرُوا إِلَى ثَمَرِهِ إِذَا أَثْمَرَ وَيَنْعِهِ إِنَّ فِي ذَلِكُمْ لَآيَاتٍ لِّقَوْمٍ يُؤْمِنُونَ
It is He who sends down water from the sky, and brings forth with it every kind of growing thing. Then from it We bring forth vegetation from which We produce the grain, in clusters, and from the palm-tree, from the spathes of it, low-hanging clusters [of dates], and gardens of grapes, olives and pomegranates, similar and dissimilar. Look at its fruit as it fructifies and ripens. Indeed, there are signs in that for a people who have faith.
Agha Ali Puya Commentary
Commentary on Quran 6:99
[Pooya/Ali Commentary 6:99] Although the source (rain) is single, but the produce is of diverse varieties. See commentary of verses 95 and 96 of this surah. In these things there are signs for people who believe in the real fruits of spiritual life. Understanding is a higher faculty than knowledge, and is necessary for knowing the meaning and purpose of this life.
