Sura Al Nisa – verse 174

“O human beings, indeed there has come to you a decisive proof, a manifest truth from you Rabb and we have also sent down to you a clear light, a clarifying light.”

Burhan is something that is so decisive that it’s undefeatable and this refers to the Prophet (pbuh). While, the noor refers to the Qur’an. So here, it is talking about the Qur’an and the masumeen, which are clear evidence of right and wrong. These are the two that we use for guidance to success.
