5:58 وَإِذَا نَادَيْتُمْ إِلَى الصَّلاَةِ اتَّخَذُوهَا هُزُواً وَلَعِباً ذَلِكَ بِأَنَّهُمْ قَوْمٌ لاَّ يَعْقِلُونَ When ye proclaim your call to prayer they take it (but) as mockery and sport; that is because they are a people without understanding. 23:21 وَإِنَّ لَكُمْ فِي الْأَنْعَامِ لَعِبْرَةً نُّسقِيكُم مِّمَّا فِي بُطُونِهَا وَلَكُمْ فِيهَا مَنَافِعُ كَثِيرَةٌ وَمِنْهَا تَأْكُلُونَ And in cattle (too) ye have an instructive example: from within their bodies We produce (milk) for you to drink; there are, in them, (besides), numerous (other) benefits for you; and of their (meat) ye eat; 24:44 يُقَلِّبُ اللَّهُ اللَّيْلَ وَالنَّهَارَ إِنَّ فِي ذَلِكَ لَعِبْرَةً لِّأُوْلِي الْأَبْصَارِ It is Allah Who alternates the Night and the Day: verily in these things is an instructive example for those who have vision!
