Hadith #1

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 abu ‘Umayr from Hammad ibn ‘Uthaman from al-Halabiy who has said the following: “I once asked abu ‘ Abd Allah, ‘Alayhi al-Salam, 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.”’
