Hadith.3209 - When you intend to visit Baghdad, if Allah (swt) wills, perform ghusl (ritual purification), cleanse yourself, and wear two clean garments. Visit their graves, and upon reaching the grave of Imam Musa ibn Jafar Al-Kadhim (as) say: "Peace be upon you, O friend of Allah (swt). Peace be upon you, O proof of Allah (swt). Peace be upon you, O light of Allah (swt) in the darkness of the earth. I have come to you as a visitor, recognizing your right, opposing your enemies, and loyal to your allies. Intercede for me with your Lord (azj)." Then, ask for your needs. Then greet Abu Ja'far (as) with the same words and invocation. When you intend to visit Imam (as) perform ghusl, cleanse yourself, and wear two clean garments. Say: "O Allah (swt), send blessings upon Muhammad ibn Ali, the Imam, the devout, the pure, the chosen, the pleasing, and Your proof over those above the earth and beneath it. Bestow abundant, flourishing, pure, blessed, continuous, successive, and uninterrupted blessings, as the best You have sent upon any of Your chosen ones. Peace be upon you, O friend of Allah (swt). Peace be upon you, O light of Allah (swt). Peace be upon you, O proof of Allah (swt). Peace be upon you, O leader of the pious, heir of the knowledge of the Prophets, and the descendant of the successors. Peace be upon you, O light of Allah (swt) in the darkness of the earth. I have come to you as a visitor, recognizing your right, opposing your enemies, and loyal to your allies. Intercede for me with your Lord (azj)." Then, ask for your needs. Afterward, pray in the dome containing Muhammad ibn Ali, peace be upon him: - Four rak'ahs with two taslims. - Two rak'ahs for the visitation of Musa, peace be upon him. - Two rak'ahs for the visitation of Muhammad ibn Ali, peace be upon him. Do not pray at the head of Musa (as) as the graves of Quraysh face you, and it is not permissible to take them as a qibla, if Allah (swt) wills.
