What is the authenticity of the Hadith attributed to the Messenger of Allah, peace and blessings be upon him, regarding the effect of weekdays on trimming nails, which states: "Whoever trims his nails on Saturday, leprosy will afflict his fingers; and whoever trims his nails on Sunday, blessings will depart from him; and whoever trims his nails on Monday, he will become a memorizer, a reciter, and a writer; and whoever trims them on Tuesday—ruin will befall him; and whoever trims them on Wednesday, he will become ill-tempered; and whoever trims them on Thursday, disease will exit him and healing will enter him; and whoever trims his nails on Friday, his lifespan will be increased"?
No hadith with the exact wording mentioned has been reported. However, specific days for trimming nails were mentioned in Al-Shawkani's book, "Al-Fawa'id Al-Majmu'ah fi Al-Ahadith Al-Mawdu'ah" (Collected Benefits Regarding Fabricated Hadith). Al-Shawkani stated that Al-Sakhawi said in "Al-Maqasid Al-Hasanah" (The Good Intentions) that nothing has been authentically established from the Prophet, peace be upon him, regarding the manner of cutting nails or specifying a day for it. He also mentioned that what is attributed to Ali or to his shaykh Ibn Hajar in this regard is false.
