Saying Something under Compulsion (Ikraah)
Bukhari :: Book 9 :: Volume 85 :: Hadith 73
Narrated 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."
