“Abu al-Hassan (a.s.), has said, ‘When you are in Baghdad, (near the gravesite of the Imam) say, ‘(I hereby declare, affirm and acknowledge that you are a ‘Alayhi al-Salam and my) submission to (your commandments), O Allah’s appointed guardian over His creatures. (I hereby declare, affirm and acknowledge that you are a ‘Alayhi al-Salam and my) submission to (your commandments), O possessor of authority of Allah. (I hereby declare, affirm and acknowledge that you are a ‘Alayhi al-Salam and my) submission to (your commandments), O light of Allah in the darkness of earth. (I hereby declare, affirm and acknowledge that you are a ‘Alayhi al-Salam and my) submission to (your commandments), O the one with whose status Allah has made commencement. I have come to you with awareness about your rights and as an enemy of your enemies. Please intercede on my behalf before your Lord.’ ‘Then pray and appeal before Allah for your needs’. He (the Imam) said, ‘You should offer your greeting of peace to abu Ja’far (a.s.), with the same expressions as the above ones.’”
