According to Tafsir ibn Kathir, the root meaning of taqwa is to avoid what one dislikes. It was reported that Umar bin Khattab asked Ubay ibn Kaab about Taqwa. Ubay said, "Have you ever walked on a path that has thorns on it?" Umar said, "Yes." Ubay asked, "What did you do then?" to which Umar replied, "I rolled up my sleeves and struggled." Ubay said, "That is taqwa, to protect oneself from sin through life’s dangerous journey so that one can successfully complete the journey unscathed by sin."
