Fasting (Kitab Al-Siyam)

Dawud :: Book 13 : Hadith 2426

Narrated Muslim al-Qurashi:

I asked or someone asked the Prophet (peace_be_upon_him) about perpetual fasting. He replied: You have a duty to your family. Fast during Ramadan and the following month, and every Wednesday and Thursday. You will then have observed a perpetual fast.
