Al-Hasan (al-Basri) would recite fatihat al-kitab in the noon and afternoon prayers while he led in prayer or he was behind the imam and would glorify Allah, and would repeatedly say: “Allah is most great” and “ There is no god but Allah” (i.e takbir and tahlil) equal to the amount one recites al-Qaf (Surah 50) and al-Dhariyat(surah 51).  

أبو داود:٨٣٤حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ حَدَّثَنَا حَمَّادٌ عَنْ حُمَيْدٍ مِثْلَهُ لَمْ يَذْكُرِ التَّطَوُّعَ قَالَ

كَانَ الْحَسَنُ يَقْرَأُ فِي الظُّهْرِ وَالْعَصْرِ إِمَامًا أَوْ خَلْفَ إِمَامٍ بِفَاتِحَةِ الْكِتَابِ وَيُسَبِّحُ وَيُكَبِّرُ وَيُهَلِّلُ قَدْرَ ق وَالذَّارِيَاتِ
