Chapter 46 | The Case of One Who Becomes a Muslim during the Month of Ramadan
1ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حَمَّادِ بْنِ عُثْمَانَ عَنِ الْحَلَبِيِّ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) أَنَّهُ سُئِلَ عَنْ رَجُلٍ أَسْلَمَ فِي النِّصْفِ مِنْ شَهْرِ رَمَضَانَ مَا عَلَيْهِ مِنْ صِيَامِهِ قَالَ لَيْسَ عَلَيْهِ إِلاَّ مَا أَسْلَمَ فِيهِ.
1. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Hammad ibn ‘Uthaman from al-Halabiy who has said the following: “I once asked abu ‘ Abd Allah , about the case of one who becomes a Muslim in the middle of the month of Ramadan, if he owes any fast. He (the Imam) said, ‘There is no fast upon him except that (day) in which he has become a Muslim.”’
