Sayyiduna Abu Hurayrah (may Allah be pleased with him) says that when the Messenger of Allah (peace and blessings be upon him) said 'Sami'a Allahu liman hamidah' in the last rak'ah of the Isha prayer, he would recite qunut after the ruku': "'Allahumma anji al-Walida bna al-Walid, Allahumma anji Ayyasha bna Abi Rabi'ah, Allahumma anji Salamata bna Hisham, Allahumma anji al-mustad'afina mina al-mu'minin, Allahumma-shdud wat'ataka ala Mudar, Allahumma-j'alha sinina ka-sini Yusuf' (O Allah, rescue al-Walid bin al-Walid; O Allah, rescue Ayyash bin Abi Rabi'ah; O Allah, rescue Salamah bin Hisham; O Allah, rescue the weak among the believers; O Allah, afflict the disbelievers of Mudar with Your severe punishment, and keep this punishment upon them for a long period like the famine of Yusuf)."
