[Machine] According to the Messenger of Allah ﷺ , a person should not be sold until the payment is received. Ibn Abbas added his opinion, saying, "And I do not think that anything should be given except in return for something of equal value."
عَنْهُ رَسُولُ اللهِ ﷺ أَنْ يُبَاعَ حَتَّى يُقْبَضَ فَالطَّعَامُ وَقَالَ ابْنُ عَبَّاسٍ بِرَأْيِهِ وَلَا أَحْسَبُ كُلَّ شَيْءٍ إِلَّا مِثْلَهُ
