The Messenger of Allah ﷺ forbade to sell spoils of war till they are appointed, and to sell palm trees till they are safe from every blight, and a man praying without tying belt.
نَهَى رَسُولُ اللَّهِ ﷺ عَنْ بَيْعِ الْغَنَائِمِ حَتَّى تُقْسَمَ وَعَنْ بَيْعِ النَّخْلِ حَتَّى تُحْرَزَ مِنْ كُلِّ عَارِضٍ وَأَنْ يُصَلِّيَ الرَّجُلُ بِغَيْرِ حِزَامٍ
