Magnificence of the Creator in birds
Nahj al-Balāgha|Volume 1|Book 1|Chapter 165
[صغار المخلوقات :] فَسُبْحَانَ مَنْ أَدْمَجَ قَوَائِمَ الذَّرَّةِ وَالْهَمَجَةِ إلَى مَا فَوْقَهُمَا مِنْ خَلْقِ الْحِيتَانِ وَالاْفْيِلَةِ! وَوَأَى عَلَى نَفْسِهِ أَلاَّ يَضْطَرِبَ شَبَحٌ مِمَّا أَوْلَجَ فِيهِ الرُّوحَ، إِلاَّ وَجَعَلَ الْحِمَامَ مَوْعِدَهُ، وَالْفَنَاءَ غَايَتَهُ.
[The magnificence of the Creator in great and small creation :] Glorified is Allāh who has assigned feet to small ants and gnats and also to those above them, the serpents and the elephants. He has made it obligatory upon Himself that no skeleton in which He infuses the spirit would move, but that death is its promised place and destruction its final end.
