Muhammad ibn Ali ibn Mahbub, from Muhammad ibn al-Husayn, from al-Hasan ibn Ali ibn Faddal, from Abu Hafs al-Jurjani, from Abu al-Khadib al-Rabi‘ ibn Bakr, from Abd al-Rahim al-Qasir, from Abu Ja’far عليه السلام, peace be upon him, who said: Imam al-Baqir عليه السلام said: “Whoever trims his nails and mustache every Friday, and says at the time of trimming: ‘In the name of Allah سبحانه وتعالى, and by Allah سبحانه وتعالى, and upon the Sunnah of the Messenger of Allah سبحانه وتعالى, may Allah سبحانه وتعالى bless him and his family’, then not a single clipping (of nail) or cutting (of hair) will fall from him, except that Allah سبحانه وتعالى will write for him with it the freeing of a soul (in rewards), And he will not fall ill except with the illness by which he dies.”
