Mishkat al-Masabih
She reported the Prophet (ﷺ) as saying, “Those who will receive the severest punishment on the day of resurrection will be they who imitate what God has created.” (Bukhari and Muslim.)
وَعَنْهَا عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «أَشَدُّ النَّاسِ عَذَابًا يَوْمَ الْقِيَامَةِ الَّذِينَ يُضَاهُونَ بِخلق الله»
