"The Messenger of Allah ﷺ bought a load of fodder from a Bedouin man. When the transaction was concluded, the Messenger of Allah ﷺ said: 'Choose (either to go ahead or to cancel the transaction).' The Bedouin said: 'May Allah grant you a long life of good transaction!"'
اشْتَرَى رَسُولُ اللَّهِ ﷺ مِنْ رَجُلٍ مِنَ الأَعْرَابِ حِمْلَ خَبَطٍ فَلَمَّا وَجَبَ الْبَيْعُ قَالَ رَسُولُ اللَّهِ ﷺ اخْتَرْ فَقَالَ الأَعْرَابِيُّ عَمْرَكَ اللَّهَ بَيِّعًا
