What is better in the Tarawih prayer: increasing the number of units or lengthening the recitation?

Question : Honorable Shaykh! A questioner says: What is better in the Tarawih prayer, increasing the number of rak'ahs and shortening the recitation, or the opposite?

Answer : The best is to adhere to the number of units that the Prophet (peace and blessings be upon him) used to stand for. That is, not to exceed thirteen or eleven rak'ahs, and not to fall short of that number.
However, if the choice is between limiting oneself to this number with prolonged standing, bowing, and prostration, or increasing the number while shortening those actions, there is no doubt that the former is better. That is, limiting oneself to eleven or thirteen rak'ahs with prolonged standing in recitation, and prolonged bowing and prostration. As for if the choice is between performing this number without lengthening the actions, or performing fewer than this number with lengthening, we say: look at what is best for your heart. But there is no doubt that adhering to the number that the Messenger (peace and blessings be upon him) used to reach is better.
