Arabic (Original)
حَدَّثَنَا حَجَّاجٌ أَخْبَرَنَا لَيْثٌ حَدَّثَنِي يَزِيدُ بْنُ أَبِي حَبِيبٍ عَنْ أَبِي الْخَيْرِ عَنْ عُقْبَةَ بْنِ عَامِرٍ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِيَّاكُمْ وَالدُّخُولَ عَلَى النِّسَاءِ فَقَالَ رَجُلٌ مِنْ الْأَنْصَارِ يَا رَسُولَ اللَّهِ أَفَرَأَيْتَ الْحَمْوَ قَالَ الْحَمْوُ الْمَوْتُ.
English Translation
Hajjaj narrated to us, Layth told us, Yazid ibn Abi Habib told me, from Abu al-Khayr, from 'Uqbah ibn 'Amir, that the Messenger of Allah, peace and blessings be upon him, said, "Beware of entering upon women." A man from the Ansar said, "O Messenger of Allah, what about the husband's brother?" He said, "The husband's brother is death [i.e., is the greatest danger]."
