٣ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ أَبِي أَيُّوبَ قَالَ سَأَلَ مُحَمَّدُ بْنُ مُسْلِمٍ أَبَا عَبْدِ الله (عَلَيْهِ الْسَّلام) وَأَنَا أَسْمَعُ عَنِ الْمُسَافِرِ إِنْ حَدَّثَ نَفْسَهُ بِإِقَامَةِ عَشَرَةِ أَيَّامٍ قَالَ فَلْيُتِمَّ الصَّلاَةَ وَإِنْ لَمْ يَدْرِ مَا يُقِيمُ يَوْماً أَوْ أَكْثَرَ فَلْيَعُدَّ ثَلاَثِينَ يَوْماً ثُمَّ لْيُتِمَّ وَإِنْ كَانَ أَقَامَ يَوْماً أَوْ صَلاَةً وَاحِدَةً فَقَالَ لَهُ مُحَمَّدُ بْنُ مُسْلِمٍ بَلَغَنِي أَنَّكَ قُلْتَ خَمْساً فَقَالَ قَدْ قُلْتُ ذَاكَ قَالَ أَبُو أَيُّوبَ فَقُلْتُ أَنَا جُعِلْتُ فِدَاكَ يَكُونُ أَقَلَّ مِنْ خَمْسٍ فَقَالَ لاَ. 
3. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from abu Ayyub who has said the following: “Muhammad ibn Muslim once asked abu ‘Abd Allah , when I was listening, about a traveler who thinks to stay for ten days. He (the Imam) said, ‘He is required to perform his Salah (prayer) as complete. If he does not know for how long he will stay, like for one or more, he can count to thirty days, then perform his Salah (prayer) as complete even if thereafter he stays for one day or one Salah (prayer).’ Muhammad ibn Muslim then said, ‘I am told that you have said it is five.’ He (the Imam) said, ‘Yes, I had said that.’ Abu Ayyub has said that he said, ‘I pray to Allah to keep my soul in service for your cause, can it be less than five?’ He (the Imam) said, ‘No, it cannot be less than five.’”
