al-Mawṣilī (d. 683)

Ḥanafī judge, says in “al-Ikhtiyār” that one should say the following during Ziyārah: “So intercede for us with your Lord...” then he mentions a very long statement, then: “Intercession! Intercession

Peace be upon you and upon your pure and noble household, whom Allah has purified and removed all impurities from. May Allah reward you with the best of rewards that He has rewarded a prophet for his people, his nation. I bear witness that you have conveyed the message, fulfilled the trust, advised the nation, clarified the proof, strived in the way of Allah, and fought until certainty came to you. May Allah bless your soul, body, and grave according to the religion of Allah, with eternal prayers until the Day of Judgment, O Messenger of Allah. We are your delegation and visitors to your grave, coming from distant lands and faraway places, seeking to fulfill your rights, behold your virtues, visit you, and seek intercession with our Lord through you. Our sins have burdened our backs, and our burdens have weighed heavily on our shoulders, and you are the intercessor promised with intercession and the praised station. Allah the Almighty has said: "And when they wrong themselves, they come to you, then seek forgiveness from Allah and the Messenger seeks forgiveness for them, they would certainly find Allah Oft-Returning, Most Merciful." [Quran 4:64]. We have come to you as wrongdoers to ourselves, seeking forgiveness for our sins, so intercede for us with your Lord, and ask Him to make us die upon your way, gather us in your group, admit us to your pool, and give us to drink from your cup without disgrace or regret. Intercession, O Messenger of Allah, say it three times. Our Lord, forgive us and our brothers who preceded us in faith." [Quran 59:10]. And deliver to him the greetings from those who entrusted him, saying: "Peace be upon you, O Messenger of Allah, from so-and-so son of so-and-so, seeking intercession with you to your Lord, so intercede for him and all the Muslims." Then stand facing his direction, and pray for him as much as you wish.
