Tafseer Ibn Kathir of YAA SIIN [1]

1. Ya Sin. 2. By the Qur'an, full of wisdom, 3. Truly, you are one of the Messengers, 4. On the straight path. 5. Sent down by the Almighty, the Most Merciful, 6. In order that you may warn a people whose forefathers were not warned, so they are heedless. 7. Indeed the Word has proved true against most of them, so they will not believe. We have already discussed the individual letters at the beginning of Surat Al-Baqarah.

(By the Qur'an, full of wisdom) means, Al-Muhkam (perfect) which falsehood cannot come to from before it or behind it.

(Truly, you) means, O Muhammad,

(are one of the Messengers, on the straight path.) means, following a straight methodology and religion, and an upright Law.

(Sent down by the Almighty, the Most Merciful.) means, this path which you have brought is a revelation from the Lord of might Who is Most Merciful to His believing servants. This is like the Ayah:

(And verily, you are indeed guiding (mankind) to the straight path. The path of Allah to Whom belongs all that is in the heavens and all that is on the earth. Verily, to Allah all matters return.) (42:52-53).

(In order that you may warn a people whose forefathers were not warned, so they are heedless.) This refers to the Arabs, for no warner had come to them before him. The fact that they alone are mentioned does not mean that others are excluded, just as mentioning some individuals does not mean that all others are excluded. We have already mentioned the Ayat and Mutawatir Hadiths which state that the mission of the Prophet is universal, when we discussed the meaning of the Ayah:

(Say: ”O mankind! Verily, I am sent to you all as the Messenger of Allah.'') (7:158).

(Indeed the Word has proved true against most of them,) Ibn Jarir said, ”The punishment has become inevitable for most of them, because Allah has decreed in the Mother of the Book (Al-Lawh Al-Mahfuz) that they will not believe.

(so they will not believe. ) in Allah, or in His Messengers.
