Dua Amulet for for knee pain relief

Quoted from the book of Tibb al-A'immah (Medicine of the Imams), Jabir al-Ju`fi reported Imam Muhammad al-Baqir (`a) as saying: — I was present with al-Husayn ibn `Ali (`a) when a man from the descendants of Umayyah, yet he was loyalist to us, came to him and said, “O son of Allah’s Messenger, I could hardly come to you walking because of a pain from which I am suffering in my leg.” — The Imam (`a) asked, “How are you turned back from the supplicatory amulet of al-Hasan ibn `Ali (`a)?” — “What is that, son of Allah’s Messenger?” asked the man. — The Imam (`a) explained, “You may recite the first seven verses of Surah al-Fath.” — Afterwards, the man said, “As I had carried out this direction, I felt no pain at all.” — It is also reported that one who suffers from knee pains may say the following supplicatory prayer after the ritual prayers:

يَا أَجْوَدَ مَنْ أَعْطَىٰ

ya ajwada man a`ta

O most magnanimous of all those who may donate!

يَا خَيْرَ مَنْ سُئِلَ

ya khayra man su'ila

O best of all those who may be besought!

وَيَا أَرْحَمَ مَنِ ٱسْتُرْحِمَ

wa ya arhama man isturhima

O most merciful of all those whose mercy is asked!

إِرْحَمْ ضَعْفِي وَقِلَّةَ حِيلَتِي

irham da`fi wa qillata hilati

(Please) have mercy upon my weakness and my confusion

وَأَعْفِنِي مِنْ وَجَعِي

wa a`fini min waja`i

and release me from my pain.

For those suffering from pains in the legs, it is reportedly recommended to recite the following holy verse seven times over the legs:

وَٱتْلُ مَا أُوحِيَ إِلَيْكَ مِنْ كِتَابِ رَبِّكَ

watlu ma uhiya ilayka min kitabi rabbika

“And recite what has been revealed to you of the Book of your Lord.

لاَ مُبَدِّلَ لِكَلِمَاتِهِ

la mubaddila likalimatihi

There is none who can alter His words

وَلَنْ تَجِدَ مِنْ دُونِهِ مُلْتَحَدًا

wa lan tajida min dunihi multahadan

and you shall not find any refuge besides Him.”
