"I heard the Messenger of Allah ﷺ say: 'The Muslim is the brother of another Muslim, and it is not permissible for a Muslim to sell his brother goods in which there is a defect, without pointing that out to him."'  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ الْمُسْلِمُ أَخُو الْمُسْلِمِ وَلاَ يَحِلُّ لِمُسْلِمٍ بَاعَ مِنْ أَخِيهِ بَيْعًا فِيهِ عَيْبٌ إِلاَّ بَيَّنَهُ لَهُ  

"I heard the Messenger of Allah ﷺ say: 'Whoever sells defective goods without pointing it out, he will remain subject to the wrath of Allah, and the angels will continue to curse him.'"  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ مَنْ بَاعَ عَيْبًا لَمْ يُبَيِّنْهُ لَمْ يَزَلْ فِي مَقْتٍ مِنَ اللَّهِ وَلَمْ تَزَلِ الْمَلاَئِكَةُ تَلْعَنُهُ
