حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ، عَنْ سُفْيَانَ، عَنْ أَبِي إِسْحَاقَ، عَنْ حَارِثَةَ، قَالَ جَاءَ نَاسٌ مِنْ أَهْلِ الشَّامِ إِلَى عُمَرَ رَضِيَ اللَّهُ عَنْهُ فَقَالُوا إِنَّا قَدْ أَصَبْنَا أَمْوَالًا وَخَيْلًا وَرَقِيقًا نُحِبُّ أَنْ يَكُونَ لَنَا فِيهَا زَكَاةٌ وَطَهُورٌ قَالَ مَا فَعَلَهُ صَاحِبَايَ قَبْلِي فَأَفْعَلَهُ وَاسْتَشَارَ أَصْحَابَ مُحَمَّدٍ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَفِيهِمْ عَلِيٌّ رَضِيَ اللَّهُ عَنْهُ فَقَالَ عَلِيٌّ هُوَ حَسَنٌ إِنْ لَمْ يَكُنْ جِزْيَةً رَاتِبَةً يُؤْخَذُونَ بِهَا مِنْ بَعْدِكَ‏.‏

Shu'bah said

I heard 'Asim bin 'Amr al-Bajali narrate from one of those who asked ‘Umar bin al-Khattab. We have come to you to ask you about three things: A man's nafl prayer in his house, Ghusl in the case of janabah, and what it is appropriate for a man to do with his wife when she is menstruating. He said: Are you magicians? You have asked me about something that no one has asked me about since I asked the Messenger of Allah (ﷺ) about it, and he said: `A man's nafl prayer in his house is light, so whoever wishes, let him illuminate his house.` And he said with regard to ghusl in the case of janabah: `Let him wash his private parts, then do wudoo', then pour water over his head three times.` And he said concerning the menstruating woman: `The [Husband may enjoy] whatever is above the izar (waist wrapper).`
