قَالَ مُصَنِّفُ هَذَا الْكِتَابِ رَحِمَهُ اللَّهُ مَنْ نَصَبَ حَرْباً لآِلِ مُحَمَّدٍ ص فَلَا نَصِيبَ لَهُ فِي الْإِسْلَامِ فَلِهَذَا حُرِّمَ نِكَاحُهُمْ.
The compiler of this book, may Allah سبحانه وتعالى have mercy on him, said: Whoever declares enmity against the family of Muhammad, peace be upon them, has no share in Islam. For this reason, their marriage has been prohibited.
