And before this, there was the Book of Moses as Guide and Mercy, and this is the Book testifying to It in the Arabic language, to warn the wrongdoers and a Glad Tiding for the Muhsins.
Muhsins are those who live here, seeing the Lord from the Book Adhikr—the Light. That means those who are living here under the Light of Adhikr. Adhikr revealed to the last Messenger Muhammad testifies and safeguards all the Books revealed to the Messengers, including the Book Thourath revealed to Moses. Just like the soul of all mankind is the same, the soul of all Books is also the same. It is called Adhikr. It will argue and witness in favour of those who live under Its Light and testify to It, and will safeguard them from calamities, disasters, diseases, and Hellfire, whereas It will argue and witness against the wrongdoers who hide It after receiving It. See explanation 2: 2; 25: 33–34; 39: 32–35; and 41: 44.
