The Peak of Eloquence · Hadith 877 (#Passage #5)

[منها في صفة خلق أصناف من الحيوان :] وَلَوْ فَكَّروا فِي عَظِيمِ الْقُدْرَةِ، وَجَسِيمِ النِّعْمَةِ، لَرَجَعُوا إِلَى الطَّرِيقِ، وَخَافُوا عَذَابَ الْحَرِيقِ، وَلكِنَّ الْقُلُوبَ عَلِيلَةٌ، وَالاَبْصَارَ مَدْخُولَةٌ! ألاَ تَنْظُرُونَ إِلَى صَغِيرِ مَا خَلَقَ اللهُ، كَيْفَ أَحْكَمَ خَلْقَهُ، وَأَتْقَنَ تَرْكِيبَهُ، وَفَلَقَ لَهُ السَّمْعَ وَالْبَصَرَ، وَسَوَّى لَهُ الْعَظْمَ وَالْبَشَرَ!.

[A part of the same sermon About the creation of animal species :] Had they pondered over the greatness of His power and the vastness of His bounty they would have returned to the right path and feared the punishment of the Fire; but hearts are sick and eyes are impure. Do they not see the small things He has created, how He strengthened their system and opened for them hearing and sight and made for them bones and skins?
