"I bear witness that the true and truly inspired one Abul-Qasim ﷺ told us: 'Selling a Muhaffalah is Khilabah, and Khilabah is not lawful for the Muslim."' (Ibn Majah said: " Meaning: 'Deception.")
أَنَّهُ قَالَ أَشْهَدُ عَلَى الصَّادِقِ الْمَصْدُوقِ أَبِي الْقَاسِمِ ﷺ أَنَّهُ حَدَّثَنَا قَالَ بَيْعُ الْمُحَفَّلاَتِ خِلاَبَةٌ وَلاَ تَحِلُّ الْخِلاَبَةُ لِمُسْلِمٍ
