When to cut nails

The Messenger of Allah (may Allah bless him and grant him peace) has said that, 'He who cuts his nails on Friday, will be in Allah's (The Exalted) protection for the following week. He who cuts his nails on a Saturday will be spared from illness, and he who cuts his nails on Sunday will have poverty taken away from him. If someone is mentally unstable then by cutting his nails on Monday, this illness will be cured. He who cuts his nails on a Tuesday will also be protected from illness. It is better not to cut nails on Wednesday as there are hadith for and against, as Imam Tahawi said, paring nails on Wednesdays can cause leprosy. To cut nails on Thursday will cure illness such as leprosy.
