Divine signs (ayat) in creation

وَإِنَّ لَكُمْ فِى ٱلْأَنْعَـٰمِ لَعِبْرَةً ۖ نُّسْقِيكُم مِّمَّا فِى بُطُونِهِۦ مِنۢ بَيْنِ فَرْثٍ وَدَمٍ لَّبَنًا خَالِصًا سَآئِغًا لِّلشَّـٰرِبِينَ

And indeed, for you in grazing livestock is a lesson. We give you drink from what is in their bellies - between excretion and blood - pure milk, palatable to drinkers.

وَءَايَةٌ لَّهُمْ أَنَّا حَمَلْنَا ذُرِّيَّتَهُمْ فِى ٱلْفُلْكِ ٱلْمَشْحُونِ

And a sign for them is that We carried their forefathers in a laden ship.
