Al – Ifaadaat Al- Ihsaaniyyah Vol 1
” I related to you in the afternoon that Allāh ta‛ālā expounded the knowledge of the past and future generations in the four books. Although countless books were revealed, Allāh ta‛ālā included all sciences in the Taurāh, Zabūr and Injīl. Furthermore, all the sciences which these books contain are encompassed in the Qur’ān. By giving the Qur’ān to Rasūlullāh sallallāhu ‛alayhi wa sallam, it is as if Allāh ta‛ālā gave him knowledge of all the past and future generations ”
