al baqarah ayat 2

In the Book of Tafsir Al Azhar compiled by Buya Hamka it is also explained,

every verse and letter that came down and began to circulate and

be memorized by the companions did not need to be doubted,

because there was nothing to doubt. "He is truly a revelation from God, brought by Jibril,

not just made up by the Apostle who is not good at writing and reading.

He is a guide for people who want to be pious or Muttaqin," 

explained Buya Hamka in his further interpretation.

According to the interpretation of Surah Al Baqarah verse 2, 

people who are pious are people who maintain and protect themselves 

from the punishment of Allah SWT by always carrying out orders and 

staying away from His prohibitions.
