"Do not go out to meet the riders, and do not bind the udders of camels and seep. Whoever has boughty anything in that manner has two choices: If he whishes he may keep it, or if he wants to return it he may return it, along with a Sa of dates." (Sahih ) (Using translation from Nasāʾī 4487)  

عَنِ النَّبِيِّ ﷺ قَالَ «لَا تَلَقَّوُا الرُّكْبَانَ لِلْبَيْعِ وَلَا تُصَرُّوا الْإِبِلَ وَالْغَنَمَ مَنِ ابْتَاعَ مِنْ ذَلِكَ شَيْئًا فَهُوَ بِخَيْرِ النَّظَرَيْنِ إِنْ شَاءَ أَمْسَكَهَا وَإِنْ شَاءَ أَنْ يَرُدَّهَا رَدَّهَا وَمَعَهَا صَاعُ مِنْ تَمْرٍ لَا سَمْرَاءَ»  

"whoever buys a Musarraha, if he is please with it when he milks it, he may keep it, and if he is not please with it, he may return it, along with a Sa of daters"' (Sahih ) (Using translation from Nasāʾī 4488)  

عَنْ رَسُولِ اللهِ ﷺ قَالَ «إِنَّ مَنِ اشْتَرَى مُصَرَّاةً فَإِنْ رَضِيَهَا إِذَا حَلَبَهَا فَلْيُمْسِكْهَا وَإِنْ كَرِهَهَا فَلْيَرُدَّهَا وَمَعَهَا صَاعٌ مِنْ تَمْرٍ»
