وَمَا خَلَقْنَا السَّمَاوَاتِ وَالْأَرْضَ وَمَا بَيْنَهُمَا إِلَّا بِالْحَقِّ ۗ وَإِنَّ السَّاعَةَ لَآتِيَةٌ ۖ فَاصْفَحِ الصَّفْحَ الْجَمِيلَ (85)
(15:85) We have not based the creation of the Earth and the Heavens and everything but truth, *47 and our judgment is sure to come. So O Muhammad, overlook . (their misbehaviour) in a gracious manner.
*47) This was to reassure the Holy Prophet that ultimately he would come out successful because he was propagating the Truth, and the whole of the universe was based on truth. Such an assurance was urgently needed because at that tithe falsehood appeared to be triumphant over the Truth. This implies, "O Prophet, do not worry at all at the apparent "success" of falsehood for this is temporary. Likewise the difficulties, the obstacles and the troubles in the way of truth are not permanent. Take courage, and have confidence in the cause of the Truth and you will triumph over falsehood because the whole system of the miverse is akin to truth and averse to falsehood. Therefore, truth is permanent and falsehood is perishable" (Please refer to E.N.'s 25 26,35-39 of Surah Ibrahim).
