In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
Allaah [The Most High] said:
يَا أَيُّهَا الْإِنسَانُ مَا غَرَّكَ بِرَبِّكَ الْكَرِيمِ
ٱلَّذِى خَلَقَكَ فَسَوَّٮٰكَ فَعَدَلَكَ
فِي أَيِّ صُورَةٍ مَّا شَاءَ رَكَّبَكَ
O man! What has made you careless concerning your Lord, the Most Generous? Who created you, fashioned you perfectly, and gave you due proportion; in whatever form He willed, He put you together. [Surah Al-Infitaar. Aayaat 6-8]
Have you [i.e. the human] become negligent regarding the rights of Allaah; or do make a mockery of the punishment He has promised [the evil doers]; or do you disbelieve in His Recompense?! Is He not the One Who created you, fashioned you perfectly in the best of forms and gave you due proportion? Is it befitting that you disbelieve in the blessings of your Lord or wilfully deny the kindness of the one who showed you kindness? Indeed, this behaviour of yours is out of nothing else, except ignorance, unjust behaviour, obstinacy and thoughtlessness. So, praise Allaah for not making your image similar to that of a dog, a donkey or what is similar to them. And because of this, Allaah said: [فِي أَيِّ صُورَةٍ مَّا شَاءَ رَكَّبَكَ -In whatever form He will, He put you together].
