٥ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ حَمَّادِ بْنِ عِيسَى عَنْ إِبْرَاهِيمَ بْنِ عُمَرَ الْيَمَانِيِّ عَنْ إِسْمَاعِيلَ بْنِ عَبْدِ الْخَالِقِ قَالَ كُنْتُ إِلَى جَنْبِ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) وَعِنْدَهُ ابْنُهُ عَبْدُ الله وَابْنُهُ الَّذِي يَلِيهِ فَقَالَ لَهُ رَجُلٌ أَصْلَحَكَ الله يَطُوفُ الرَّجُلُ عَنِ الرَّجُلِ وَهُوَ مُقِيمٌ بِمَكَّةَ لَيْسَ بِهِ عِلَّةٌ فَقَالَ لا لَوْ كَانَ ذَلِكَ يَجُوزُ لأَمَرْتُ ابْنِي فُلاناً فَطَافَ عَنِّي سَمَّى الأَصْغَرَ وَهُمَا يَسْمَعَانِ. 
5. Ali ibn Ibrahim has narrated from his father from Hammad ibn ‘Isa from Ibrahim ibn ‘Umar al-Yemaniy from ‘Isma‘il ibn ‘Abd al- Khaliq who has said the following: “I was next to abu ‘Abd Allah , and with him (the Imam) was his son ‘Abd Allah and his other son born after him. A man asked him (the Imam), ‘May Allah keep you well, can a man perform Tawaf for a man who lives in Makkah and who has no difficulties?’ He (the Imam) said, ‘No, if that was permissible I would have asked my son so and so’ - mentioned the name of the smaller one - ‘to perform Tawaf on my behalf’- children were listening.’”
