The Prophet ﷺ passed by me at a place called Al-Abwa or Waddan, and was asked whether it was permissible to attack the pagan warriors at night with the probability of exposing their women and children to danger. The Prophet ﷺ replied, "They (i.e. women and children) are from them (i.e. pagans)." I also heard the Prophet ﷺ saying, "The institution of Hima is invalid except for Allah and His Apostle."  

مَرَّ بِيَ النَّبِيُّ ﷺ بِالأَبْوَاءِ أَوْ بِوَدَّانَ وَسُئِلَ عَنْ أَهْلِ الدَّارِ يُبَيَّتُونَ مِنَ الْمُشْرِكِينَ فَيُصَابُ مِنْ نِسَائِهِمْ وَذَرَارِيِّهِمْ قَالَ هُمْ مِنْهُمْ وَسَمِعْتُهُ يَقُولُ لاَ حِمَى إِلاَّ لِلَّهِ وَلِرَسُولِهِ ﷺ
