﴿ فَلَا يَصُدَّنَّكَ عَنْهَا مَن لَّا يُؤْمِنُ بِهَا وَٱتَّبَعَ هَوَىٰهُ فَتَرْدَىٰ ﴾

“Hence, let not anyone who does not believe in its coming and follows [but] his own desires divert thee from [belief in] it, lest thou perish!”

فَلَا يَصُدَّنَّكَ عَنْهَا (must not make you neglectful of it - 20:16 ) Here Sayyidna Musa (علیہ السلام) is cautioned by Allah Ta’ ala lest he should allow himself to be led away by the infidels and become negligent about the Day of Judgment because that would be the cause of his ruination. It is clear that a Prophet and a Messenger who is impeccable cannot commit such a lapse but the fact that such a warning has been addressed to him is meant to warn his followers as well as mankind at large to be cautious in the matter
