1ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ الْحُسَيْنِ بْنِ سَعِيدٍ عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ أَبِي حَمْزَةَ عَنْ أَبِي بَصِيرٍ قَالَ إِذَا قَدِمْتَ أَرْضاً وَأَنْتَ تُرِيدُ أَنْ تُقِيمَ بِهَا عَشَرَةَ أَيَّامٍ فَصُمْ وَأَتِمَّ وَإِنْ كُنْتَ تُرِيدُ أَنْ تُقِيمَ أَقَلَّ مِنْ عَشَرَةِ أَيَّامٍ فَأَفْطِرْ مَا بَيْنَكَ وَبَيْنَ شَهْرٍ فَإِذَا بَلَغَ الشَّهْرُ فَأَتِمَّ الصَّلاةَ وَالصِّيَامَ وَإِنْ قُلْتَ أَرْتَحِلُ غُدْوَةً.

1. A number of our people have narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa’id from al-Qasim ibn Muhammad from Ali ibn abu Hamzah forms who has said the following: “He (the Imam), ‘Alayhi al-Salam, has said, ‘If you arrive in a land where you want to stay for ten days, you must fast. You must perform your Salat (prayer) complete, but if you want to stay for less than ten days, then stop fasting. You can continue until a month and when your stay becomes one month, then complete your Salat (prayer) and fast even if you say, ‘I leave tomorrow.’”

2. Muhammad ibn Yahya has narrated from al-‘Amrakiy ibn Ali from Ali ibn Ja’far who has said the following: “I once asked abu al-Hassan, ‘Alayhi al-Salam, about a man who finds himself in the month of Ramadan during a journey and stays at a place for few days, if he is required to fast. He (the Imam) said, ‘No, he is not obligated to fast until he decides to stay for ten days. Once he makes such a decision, he is then required to fast and must perform his Salat (prayer) complete.’ I then asked him (the Imam), ‘Alayhi al-Salam, about a man who owes several days fast of the month of Ramadan, if he can carry out Qada’ (compensatory fast) of such fast at a place where he has decided to stay. He (the Imam) said, ‘No, until he decides to stay at a place for ten days.’”
