Hadith 4922ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ هَارُونَ بْنِ مُسْلِمٍ عَنْ مَسْعَدَةَ بْنِ صَدَقَةَ عَنْ أَبِي عَبْدِ الله عَنْ آبَائِهِ (عَلَيْهِم السَّلاَم) أَنَّ عَلِيّاً صَلَوَاتُ الله عَلَيْهِ كَانَ يَقُولُ فِي رَجُلٍ أَسْلَمَ فِي نِصْفِ شَهْرِ رَمَضَانَ إِنَّهُ لَيْسَ عَلَيْهِ إِلاَّ مَا يَسْتَقْبِلُ.
2. Ali ibn Ibrahim has narrated from Harun ibn Muslim from Mas’adah ibn Sadaqah who has said the following: “Abu ‘Abd Allah (a.s.), has said that ’Amir al-Mu’minin, Ali ‘Alayhi al-Salam, about one who accepts Islam in the middle of the month of Ramadan would say that he is not obligated for anything of fasting except for the coming days.”
