Narrated Abu Huraira: When the Prophet said, Sami' al-lahu liman hamidah (Allah heard him who sent his praises to Him) in the last rak`a of the `Isha' prayer, he used to invoke Allah, saying, O Allah! Save `Aiyash bin Abi Rabi`a; O Allah! Save Al-Walid bin Al-Walid; O Allah! Save the weak people among the believers; O Allah! Be hard on the Tribe of Mudar; O Allah! Inflict years of drought upon them like the years (of drought) of the Prophet Joseph.
