An Nahl Ayah 79

أَلَمْ يَرَوْاْ إِلَى ٱلطَّيْرِ مُسَخَّرَٲتٍ فِى جَوِّ ٱلسَّمَآءِ مَا يُمْسِكُهُنَّ إِلَّا ٱللَّهُ‌ۗ إِنَّ فِى ذَٲلِكَ لَأَيَـٰتٍ لِّقَوْمٍ يُؤْمِنُونَ ٧٩ Have they not seen the birds glide in the open sky? None holds them up except Allah. Surely in this are signs for those who believe.
