عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ خَالِدٍ عَنْ أَبِيهِ عَنْ أَبِي الْجَهْمِ عَنْ أَبِي خَدِيجَةَ قَالَ قَالَ لِي أَبُو عَبْدِ اللَّهِ ( عليه السلام ) كَمْ بَيْنَكَ وَ بَيْنَ الْبَصْرَةِ قُلْتُ فِي الْمَاءِ خَمْسٌ إِذَا طَابَتِ الرِّيحُ وَ عَلَى الظَّهْرِ ثَمَانٍ وَ نَحْوُ ذَلِكَ فَقَالَ مَا أَقْرَبَ هَذَا تَزَاوَرُوا وَ يَتَعَاهَدُ بَعْضُكُمْ بَعْضاً فَإِنَّهُ لَا بُدَّ يَوْمَ الْقِيَامَةِ مِنْ أَنْ يَأْتِيَ كُلُّ إِنْسَانٍ بِشَاهِدٍ يَشْهَدُ لَهُ عَلَى دِينِهِ وَ قَالَ إِنَّ الْمُسْلِمَ إِذَا رَأَى أَخَاهُ كَانَ حَيَاةً لِدِينِهِ إِذَا ذَكَرَ اللَّهَ عَزَّ وَ جَلَّ .
496. A number of our companions, from Ahmad Bin Muhammad Bin Khalid, from his father, from Al-Jaham, from Abu Khadija who said: Abu Abdullah  said to me; ‘How much (distance is there) between you and Al-Basra?’ I said, ‘It is five (days) by the water (sea) if the wind is good, and upon the back (of the earth) eight days or approximate to that’. So he  said: ‘This is not near. Visit each other frequently for there will not be an escape on the Day of Judgement from each human being to bring a witness who would testify for him upon his Religion’. And said: ‘If a Muslims sees his brother, it is a revival for his Religion if he Mentions Allah (azwj) (during their meeting)’.
