Tafsir of An-Nisa' 4:68

"And We would have guided them to a straight path."

It is the levels following faith, whose doors are opened for those who act. Abu Nu'aym recorded in al-Hilyah from Anas, who said: The Messenger of Allah (may Allah, the Exalted, bless him and grant him peace) said: "Whoever acts upon what he knows, Allah, the Exalted, will cause him to inherit knowledge of what he does not know."

Al-Juba'i said: The meaning is, "And We would have guided them in the Hereafter to the path to Paradise."
