What are the things we should do, study, or incorporate into our daily lives to ensure we can answer the three questions in our grave with quick and accurate responses? How long will it take for our hearts to learn or internalize these answers?
We must submit to the Truth and believe in Allah being The Only God, all His messengers and the 12 divine successors after the Prophet Muhammad (SAWA) about whom the Prophet has mentioned and ordered every Muslim to keep following Quran and Ahlul Bayt (AS).
We need to follow and practice the orders of Allah and the Prophet and Ahlul Bayt and avoid sinful acts.
Wassalam.
