Sayyiduna Abu Hurayrah (may Allah be pleased with him) says: By Allah, I will lead you in a prayer that most closely resembles the prayer of the Messenger of Allah (peace and blessings be upon him). He (may Allah be pleased with him), in the last rak'ah of the Zuhr, Isha and Fajr prayers, after saying 'Sami'a Allahu liman hamidah' (Allah has heard the one who praised Him), would supplicate for the believers and supplicate against the disbelievers.
