In the concluding verse (15:22), it has been reaffirmed that salvation in the Hereafter is the lot of those who believe in Him and in all of His prophets as well. Therefore, the Holy Prophet ﷺ said:
اِنَ القُرٰانَ یُفَسِرُ بعصُہ بَعضاً
One part of the Qur'an explains the other.
It is not permissible for anyone to explain the Qur'an in any way contrary to the Tafsir of the Qur'an itself.
