A: One must learn what is required of the Arabic language in order to perform the daily prayers, such as the obligatory recitation of Suratul-Fatiha and another full chapter after it as well as the recitations in the prostrations and bowings. Actually, one should learn Arabic and stay connected with it in a way which facilitates for him understanding the Holy Qur'an and the traditions of the Prophet and Infallible Imams (peace be upon them all), as well as their great legacies, which includes their supplications, sermons, ethical teaching, etc. This has a great impact on strengthening the roots of faith and on firming it in one’s soul in a way which manifests itself in conduct and behavior. The thirteenth chapter of the Introduction contains useful information in this regard.
