Tafsir

الَّذِينَ لاَ يُؤْمِنُونَ بِآيَـتِ اللَّهِ(Verily, those who do not believe in Allah's Ayat,) Allah will not guide them, and theirs will be a painful punishment, meaning, the disbelievers and heretics who are known to the people as liars. The Messenger Muhammad ﷺ, on the other hand, was the most honest and righteous of people, the most perfect in knowledge, deeds, faith and conviction. He was known among his people for his truthfulness and no one among them had any doubts about that - to such an extent that they always addressed him as Al-Amin (the Trustworthy) Muhammad. Thus when Heraclius, the king of the Romans, asked Abu Sufyan about the attributes of the Messenger of Allah ﷺ, one of the things he said to him was, "Did you ever accuse him of lying before he made his claim" Abu Sufyan said, "No". Heraclius said, "He would refrain from lying about people and then go and fabricate lies about Allah"

Sequence of Verses

In the previous verse (98), there was an instruction to say اَعُوذ بِاللہ 'a udhu bil-lah' (I seek protection with Allah) while reciting the Qur’ an which indicates that the Shaitan puts scruples in the heart when one recites the Qur'an. In the verses cited above, there is a refutation of such Satanic instigations.

إن الكفار الذين لا يصدقون بالقرآن لا يوفقهم الله لإصابة الحق، ولهم في الآخرة عذاب مؤلم موجع.

يخبر تعالى أنه لا يهدي من أعرض عن ذكره وتغافل عما أنزله على رسوله ، ولم يكن له قصد إلى الإيمان بما جاء من عند الله ، فهذا الجنس من الناس لا يهديهم الله إلى الإيمان بآياته وما أرسل به رسله في الدنيا ، ولهم عذاب أليم موجع في الآخرة .
