Needing Major Ablution
مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ وَ مُحَمَّدُ بْنُ إِسْمَاعِيلَ عَنِ الْفَضْلِ بْنِ شَاذَانَ جَمِيعاً عَنْ صَفْوَانَ بْنِ يَحْيَى عَنِ الْعَلَاءِ بْنِ رَزِينٍ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَحَدِهِمَا ( عليهما السلام ) قَالَ سَأَلْتُهُ عَنْ غُسْلِ الْجَنَابَةِ فَقَالَ تَبْدَأُ بِكَفَّيْكَ فَتَغْسِلُهُمَا ثُمَّ تَغْسِلُ فَرْجَكَ ثُمَّ تَصُبُّ الْمَاءَ عَلَى رَأْسِكَ ثَلَاثاً ثُمَّ تَصُبُّ الْمَاءَ عَلَى سَائِرِ جَسَدِكَ مَرَّتَيْنِ فَمَا جَرَى عَلَيْهِ الْمَاءُ فَقَدْ طَهُرَ
Muhammad Bin Yahya, from Muhammad Bin Al Husayn and Muhammad Bin Ismail, from Al Fazl Bin Shazaan, altogether from Safwan Bin Yahya, from Al A’ala Bin Razeyn, from Muhammad Bin Muslim,
(It has been narrated) from one of the two (5th or 6th Imam-asws) who said, ‘I asked him-asws about washing for the sexual impurity, so he-asws said: ‘Begin with your two palms, then wash your private part. Then pour water upon your head three times, then pour the water upon the rest of your body, twice. So whatever the water flows upon, so it has been purified’’.[1]
