(13) باب ذِكْرِ الْعِلَّةِ الَّتِي مِنْ أَجْلِهَا نَهَى عَنِ الْخَلِيطَيْنِ وَهِيَ لِيَقْوَى أَحَدُهُمَا عَلَى صَاحِبِهِ
It was narrated that Anas bin Malik said:
"The Messenger of Allah [SAW] forbade us to soak two things together when one is more potent than the other. I asked him about Fadikh (a drink made from fresh dates cut open) and he forbade it. He disliked the extra bit on Al-Busr, fearing that that might make it two things, so we used to cut it off."
