“Once I went to see Abu ‘Abdillah (a.s.) 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 (a) hand, (b) head and (c) feet).”’
