Hannan b. Jabir narrated from Muhammad b ‘Ali al-Sayrafi from at-Husayn al-Ashqar from 'Amr b. Abu al-Miqdam from Muhammad al-Baqir, peace be upon him, who said: ‘I was with al-Husayn b. 'Ali, peace be upon him, when one of our Shi’a from the Bani Umayya came to him and said: “O son of the Messenger of Allah, I was hardly able to walk to you because of the pain in my feet.” He said: “What about the invocation of al-Husayn b. ‘Ali?” The man said: “O son of the Messenger of Allah, and what is that?” He replied: “The verses are:
Surely We have given thee a manifest victory, that God may forgive thee thy former and thy latter sins, and complete His blessing upon thee, and guide thee on a straight path, and that God may help thee with mighty help.
It is He who sent down the Shechina into the hearts of the believers, that, they might add faith to their faith — to God belong the hosts of the heavens and the earth; God is All-knowing, All-wise — and that He may admit the believers, men and women and women alike, into gardens underneath which rivers flow, therein to dwell forever, and acquit them of their evil deeds.
That is in God's sight a mighty triumph, that He may chastise the hypocrites, men and women alike, and the idolaters, men and women alike, and those who think evil thoughts of God. Against them shall be the evil turn of fortune. God is wroth with them, and has cursed them, and has prepared for them Hell - -an evil homecoming! To God belong the hosts of the heavens and the earth; God is All-mighty, All-wise (48:1-7).”
The man said: “I did as he instructed and did not experience any of the pain after that, with the help of Allah, the Exalted.”’
