Sahih Bukhari Volume 9, Book 85, Hadith Number 73.

Narrated By Abi Huraira : The Prophet used to invoke Allah in his prayer, “O Allah! Save ‘Aiyash bin Abi Rabi’a and Salama bin Hisham and Al-Walid bin Al-Walid; O Allah! Save the weak among the believers; O Allah! Be hard upon the tribe of Mudar and inflict years (of famine) upon them like the (famine) years of Joseph.”
