Am I sinful for refusing to lead the Tarawih prayer in the mosques of my hometown, despite my ability to do so, and only leading it in emergency situations?

We congratulate you on memorizing the Quran and ask God to safeguard it for you from oblivion. We advise you to review it and teach it, for the Prophet, peace and blessings be upon him, said: "The best among you is he who learns the Quran and teaches it." We also advise you to respond to those who wish to pray behind you and benefit from your recitation.
