“We used to recite the Opening of the Book and a Surah behind the Imam in the first two Rak’ah of the Zuhr and the ‘Asr, and in the last wo Rak’ah (we would recite) the Opening of the Book.” (Using translation from Ibn Mājah 843)
أَنْ يُقْرَأَ خَلْفِ الْإِمَامِ فِي الرَّكْعَتَيْنِ الْأُولَيَيْنِ بِفَاتِحَةِ الْكِتَابِ وَسُورَةٍ وَفِي الْأُخَرَيَيْنِ بِفَاتِحَةِ الْكِتَابِ» صحيح
