Hazrat Ibn Abi Mulaikah says that I used to lead people in Tarawih prayers during Ramadan. In one rak'ah, I would recite Surah Fatir or a similar surah. I have not heard of anyone making this a regular practice.

Hazrat Waqa says that Hazrat Saeed bin Jubair used to recite twenty-five verses in each rak'ah of Tarawih.

Hazrat Imran bin Hadeer narrates that Hazrat Abu Mujliz used to lead his people in prayer during Ramadan and would complete the recitation of the Holy Qur'an every seven days.

Hazrat Iraq bin Malik narrates that I saw such people in Ramadan for whom ropes were tied, and due to the long standing (in prayer), they would lean on them for support when they became tired.

Hasan says that whoever leads people in prayer during Ramadan should consider ease for them; if he is one who recites slowly, he should complete the Qur'an once, if he recites at a moderate pace, he should complete one and a half Qur'ans, and if he recites quickly, he should complete the Qur'an twice.
