وَقَدْ مَكَرَ الَّذِينَ مِنْ قَبْلِهِمْ فَلِلَّهِ الْمَكْرُ جَمِيعًا يَعْلَمُ مَا تَكْسِبُ كُلُّ نَفْسٍ وَسَيَعْلَمُ الْكُفَّارُ لِمَنْ عُقْبَى الدَّارِ ﴿۴۲﴾ وَيَقُولُ الَّذِينَ كَفَرُوا لَسْتَ مُرْسَلًا قُلْ كَفَى بِاللَّهِ شَهِيدًا بَيْنِي وَبَيْنَكُمْ وَمَنْ عِنْدَهُ عِلْمُ الْكِتَابِ ﴿۴۳﴾

﴾42﴿ Wa qad makaral lazeena min qablihim falillaahil makru jamee'aa; ya'lamu maa taksibu kullu nafs; wa sa ya'lamul kuffaaru liman 'uqbad daar
﴾43﴿ Wa yaqoolul lazeena kafaroo lasta mursalaa; qul kafaa billaahi shaheedam bainee wa bainakum wa man 'indahoo 'ilmul Kitaab

﴾42﴿ And surely, those before them also plotted, but the entire plan belongs to Allah. He knows what every soul earns, and soon the disbelievers will know for whom is the best end in the Hereafter
﴾43﴿ And those who disbelieve say, You are not a messenger. Say, Sufficient is Allah as a witness between me and you, and also those who have knowledge of the Book

[42] This verse indicates that the punishment of Allah cannot be prevented or repelled by anyone’s plots or strategies.
The phrase “فَلِلَّهِ الْمَكْرُ جَمِيعًا” means: Whether the plot (makr) is good or evil, its outcome and impact are entirely under Allah’s control.
So even if people plan and scheme, whether in favor of truth or against it, nothing succeeds or fails except by the will of Allah. This is a reminder that ultimate power and planning belong solely to Him.
[43] In this verse, there is a rebuke of those who deny the prophethood, and also an affirmation of the Prophet’s truthfulness through the testimony of Allah Himself.
Similar affirmations are found in: Surah Al-‘Ankabūt (29:52) Surah Al-Aḥqāf (46:8)
Regarding the phrase “وَمَنْ عِندَهُ عِلْمُ الْكِتَابِ” (And whoever possesses knowledge of the Book), there are several interpretations:
1. It refers to the believing individuals among the People of the Book, as also mentioned earlier in verse 36 of this surah.
2. It may refer to Jibrīl (peace be upon him), who brought the revelation and possesses full knowledge of it.
3. It could refer to all believers, and “the Book” here means the Qur’an.
4. Another interpretation is that the phrase is a form of oath (qasam) — meaning: By the One who possesses knowledge of the entire Book — referring to Allah Himself.
All these interpretations emphasize that the truth of the Prophet’s message is established — either by divine testimony, the knowledge of the angels, or the understanding of those familiar with previous scriptures.
