Hadith 11583ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ الْحُسَيْنِ بْنِ سَعِيدٍ عَنِ النَّضْرِ بْنِ سُوَيْدٍ عَنْ أَبِي الْحَسَنِ (عَلَيْهِ السَّلاَم) قَالَ سَأَلْتُهُ عَنِ الرَّجُلِ يَغْتَسِلُ لِلإِحْرَامِ ثُمَّ يَنَامُ قَبْلَ أَنْ يُحْرِمَ قَالَ عَلَيْهِ إِعَادَةُ الْغُسْلِ.
3. A number of our people have narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa‘id from al-Nadr ibn Suwayd who has said the following: “I once asked abu al-Hassan (a.s.), about a man who takes Ghusl (bath) for Ihram but then goes to sleep before assuming the state of Ihram. He (the Imam) said, ‘He is required to do Ghusl (bath) again.’”
