Narrated Ibn Abi `Aufa: Allah's Apostle asked for Allah's wrath upon the Ahzab (confederates), saying, "O Allah, the Revealer of the Holy Book, and the One swift at reckoning! Defeat the confederates; Defeat them and shake them."

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."

Narrated Anas: The Prophet sent a Sariya (an army detachment) consisting of men called Al-Qurra', and all of them were martyred. I had never seen the Prophet so sad over anything as he was over them. So he said Qunut (invocation in the prayer) for one month in the Fajr prayer, invoking for Allah's wrath upon the tribe of 'Usaiya, and he used to say, "The people of 'Usaiya have disobeyed Allah and His Apostle."

Narrated `Aisha: The Jews used to greet the Prophet by saying, "As-Samu 'Alaika (i.e., death be upon you), so I understood what they said, and I said to them, "As-Samu 'alaikum wal-la'na (i.e. Death and Allah's Curse be upon you)." The Prophet said, "Be gentle and calm, O `Aisha, as Allah likes gentleness in all affairs." I said, "O Allah's Prophet! Didn't you hear what they said?" He said, "Didn't you hear me answering them back by saying, 'Alaikum (i.e., the same be upon you)?"

Narrated `Ali bin Abi Talib: We were in the company of the Prophet on the day (of the battle) of Al-Khandaq (the Trench). The Prophet said, "May Allah fill their (the infidels') graves and houses with fire, as they have kept us so busy that we could not offer the middle prayer till the sun had set; and that prayer was the `Asr prayer."
