٤ـ أَحْمَدُ بْنُ مُحَمَّدٍ عَنِ الْحَجَّالِ عَنِ ابْنِ سِنَانٍ قَالَ كَتَبَ أَبِي إِلَى أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) وَكَانَ يَقْضِي شَهْرَ رَمَضَانَ وَقَالَ إِنِّي أَصْبَحْتُ بِالْغُسْلِ وَأَصَابَتْنِي جَنَابَةٌ فَلَمْ أَغْتَسِلْ حَتَّى طَلَعَ الْفَجْرُ فَأَجَابَهُ (عَلَيْهِ السَّلاَم) لا تَصُمْ هَذَا الْيَوْمَ وَصُمْ غَداً.
4. Ahmad ibn Muhammad has narrated from al-Hajjal from ibn Sinan who has said the following: “My father, once, when doing Qada’ (compensatory fast) of the fast of the month of Ramadan, wrote to abu ‘Abd Allah , and asked, ‘I, up till the morning, had Ghusl (bath); then experienced sexual relation (because of which Ghusl (bath) is obligatory) and I did not do Ghusl (bath) until it was dawn. He (the Imam) said, ‘Do not fast that day, fast the next day.’”
