1. 13:17 أَنزَلَ مِنَ ٱلسَّمَآءِ مَآءً فَسَالَتْ أَوْدِيَةٌۢ بِقَدَرِهَا فَٱحْتَمَلَ ٱلسَّيْلُ زَبَدًا رَّابِيًا وَمِمَّا يُوقِدُونَ عَلَيْهِ فِى ٱلنَّارِ ٱبْتِغَآءَ حِلْيَةٍ أَوْ مَتَٰعٍ زَبَدٌ مِّثْلُهُۥ كَذَٰلِكَ يَضْرِبُ ٱللَّهُ ٱلْحَقَّ وَٱلْبَٰطِلَ فَأَمَّا ٱلزَّبَدُ فَيَذْهَبُ جُفَآءً وَأَمَّا مَا يَنفَعُ ٱلنَّاسَ فَيَمْكُثُ فِى ٱلْأَرْضِ كَذَٰلِكَ يَضْرِبُ ٱللَّهُ ٱلْأَمْثَالَ

   He sends down water from the cloud, then watercourses flow (with water) according to their measure, and the torrent bears along the swelling foam, and from what they melt in the fire for the sake of making ornaments or apparatus arises a scum like it; thus does Allah compare truth and falsehood; then as for the scum, it passes away as a worthless thing; and as for that which profits the people, it tarries in the earth; thus does Allah set forth parables.
   

2. 34:12 وَلِسُلَيْمَٰنَ ٱلرِّيحَ غُدُوُّهَا شَهْرٌ وَرَوَاحُهَا شَهْرٌ وَأَسَلْنَا لَهُۥ عَيْنَ ٱلْقِطْرِ وَمِنَ ٱلْجِنِّ مَن يَعْمَلُ بَيْنَ يَدَيْهِ بِإِذْنِ رَبِّهِۦ وَمَن يَزِغْ مِنْهُمْ عَنْ أَمْرِنَا نُذِقْهُ مِنْ عَذَابِ ٱلسَّعِيرِ

   And (We made) the wind (subservient) to Sulaiman, which made a month's journey in the morning and a month's journey m the evening, and We made a fountain of molten copper to flow out for him, and of the jinn there were those who worked before him by the command of his Lord; and whoever turned aside from Our command from among them, We made him taste of the punishment of burning.
   

3. 34:16 فَأَعْرَضُوا۟ فَأَرْسَلْنَا عَلَيْهِمْ سَيْلَ ٱلْعَرِمِ وَبَدَّلْنَٰهُم بِجَنَّتَيْهِمْ جَنَّتَيْنِ ذَوَاتَىْ أُكُلٍ خَمْطٍ وَأَثْلٍ وَشَىْءٍ مِّن سِدْرٍ قَلِيلٍ

   But they turned aside, so We sent upon them a torrent of which the rush could not be withstood, and in place of their two gardens We gave to them two gardens yielding bitter fruit and (growing) tamarisk and a few lote-trees.
