الَّذِينَ آتَيْنَاهُمُ الْكِتَابَ يَتْلُونَهُ حَقَّ تِلَاوَتِهِ أُولَئِكَ يُؤْمِنُونَ بِهِ وَمَن يَكْفُرْ بِهِ فَأُولَئِكَ هُمُ الْخَاسِرُونَ
Those to whom We have given the Book follow it as it ought to be followed: they have faith in it. As for those who deny it—it is they who are the losers.
Agha Ali Puya Commentary
Commentary on Quran 2:121
[Pooya/Ali Commentary 2:121] The Quran was given to the Holy Prophet and those who were his flesh and blood. Their spirit was one. They were created from one light. They are his Ahl ul Bayt. See "the essentials for the readers of the Quran" on pages 1 to 7. The Holy Prophet had said: "Ali's flesh is my flesh. Ali's blood is my blood". "I and Ali are of one and the same light". According to the verse of Mubahilah (Ali Imran: 61) Ali was the nafs (self) of the Holy Prophet. It was Ali who stood by the Holy Prophet and protected him in the battle of Uhad when all his companions ran away. In all the battles which guided the course of Islamic history, it was Ali who won victories for the Muslims. It is evident from these and other incidents in history that only the Holy Prophet and his Ahl ul Bayt (the Imams in his progeny) are those who studied and followed the book as it ought to be done, and it is only they who are referred to in this verse.
