What is recited in each of the five daily prayers for reassurance?

The worshiper recites the Opening of the Book (Surat Al-Fatihah) in every rak'ah. In the Fajr prayer and the first two rak'ahs of other prayers, he recites whatever is easy for him, based on the Prophet's (peace be upon him) saying: "When you face the Qiblah, say 'Allahu Akbar,' then recite the Mother of the Qur'an, then recite whatever you wish." It was his (peace be upon him) practice not to specify a particular surah except on Fridays and the two 'Eids. He used to recite the entire surah, and sometimes he would recite it across two rak'ahs, or he would recite the beginning of the surah. It is not preserved from him that he recited the ends or middles of surahs.
