[Machine] The Prophet of Allah ﷺ prohibited mixing one thing with another, but rather each one should be kept separately.  

أحمد:٢٢٥٢١ – حَدَّثَنَا عَبْدُ الْأَعْلَى عَنْ مَعْمَرٍ عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ عَنْ عَبْدِ اللهِ بْنِ أَبِي قَتَادَةَ عَنْ أَبِي قَتَادَةَ

أَنَّ نَبِيَّ اللهِ ﷺ نَهَى أَنْ يُخْلَطَ شَيْءٌ مِنْهُ بِشَيْءٍ وَلَكِنْ لِيُنْتَبَذْ كُلُّ وَاحِدٍ مِنْهُمَا عَلَى حِدَةٍ
