4. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from al-Hajjal from Yunus ibn Ya’qub who has said the following: “Once I went to see Abu ‘Abdillah عليه السلام and I asked, ‘Can I kiss your hand, please?’ The Imam agreed and I kissed his hand. I then asked, ‘May Allah keep my soul in service for your cause, can I kiss your head, please?’ The Imam agreed and I kissed his head. Then I asked, ‘Can I kiss your feet, please?’ The Imam said, ‘You had vowed, you had vowed, you had vowed, three and one remains, one remains, and one remains.” (The Imam perhaps indicated that the narrator, in fact, had vowed to kiss the Imam’s عليه السلام hand, (b) head and (c) feet).”’
