سَنُرِيهِمۡ ءَايَٰتِنَا فِي ٱلۡأٓفَاقِ وَفِيٓ أَنفُسِهِمۡ حَتَّىٰ يَتَبَيَّنَ لَهُمۡ أَنَّهُ ٱلۡحَقُّۗ أَوَلَمۡ يَكۡفِ بِرَبِّكَ أَنَّهُۥ عَلَىٰ كُلِّ شَيۡءٖ شَهِيدٌ

We will show them Our signs in the horizons and within themselves until it becomes clear to them that it is the truth. But is it not sufficient concerning your Lord that He is, over all things, a Witness?

Fussilat · 41:53Makkah

Signs on the horizons and inside yourselves.

Proof outside and within, and Allah as Witness

Where the signs are
the horizonsevents in the world
within themselvestheir own bodies, lives
until
it is clearthis is the truth
What is enough
more proof first
He is Witnessover all things

Mujahid and others said the signs included events like Badr and the conquest of Makkah, which the Quraysh lived through. Ibn Kathir adds it may mean the human body and its design, showing the Creator's wisdom. And Allah is enough as a Witness.

Your heartbeat, without you asking. The way your cut healed by itself. The turn in your life you never planned. Signs, inside and around you. You have been reading them all along without noticing.

I would believe more firmly if I saw a clear sign.

Signs are already in the world and in my own body. Allah is witness over everything.

Try this

Put your hand on your chest for a minute today, feel your heartbeat, and say alhamdulillah.

Tafsir Ibn Kathir (shared passage from 41:52)

Say: "Tell me, if it is from Allah, and you disbelieve in it Who is more astray than one who is in opposition far away. (52)We will show them Our signs in the universes, and within themselves, until it becomes manifest to them that this is the truth. Is it not sufficient in regard to your Lord that He is a Witness over all things (53)Lo, Verily, they are in doubt concerning the meeting with their Lord. Verily, He is surrounding all things (54)

The Qur'an and the Proofs of its Truth

Allah says:

قُلْ 

(Say) – 'O Muhammad, to these idolators who disbelieve in the Qur'an'–

أَرَأَيْتُمْ إِنْ كَانَ

(Tell me, if it) – this Qur'an –

 مِنْ عِنْدِ اللَّهِ ثُمَّ كَفَرْتُمْ بِهِ

(is from Allah, and you disbelieve in it?) means, 'what do you think your position is before the One Who revealed it to His Messenger?' Allah says:

مَنْ أَضَلُّ مِمَّنْ هُوَ فِي شِقَاقٍ بَعِيدٍ

(Who is more astray than one who is in opposition far away.) means, he is in a state of disbelief, stubbornness and opposition to the truth, and is following a path that leads far away from guidance. Then Allah says:

سَنُرِيهِمْ آيَاتِنَا فِي الْآفَاقِ وَفِي أَنْفُسِهِمْ 

(We will show them Our signs in the universe, and within themselves,) meaning, 'We will show them Our evidence and proof that the Qur'an is true and has indeed been sent down from Allah to the Messenger of Allah, through external signs,

فِي الْآفَاقِ

(in the universe), ' such as conquests and the advent of Islam over various regions and over all other religions. Mujahid, Al-Hasan and As-Suddi said, "And signs within themselves means, the battle of Badr, the conquest of Makkah, and other events which befell them, where Allah granted victory to Muhammad ﷺ and his Companions, and inflicted a humiliating defeat on falsehood and its followers." It may also be that what is meant here is man and his physical composition. As detailed in the science of anatomy, which indicates the wisdom of the Creator – may He be blessed and exalted – and the different inclinations and opposite natures that people have, good and bad, etc., and the (divine) decrees to which man is subjected, having no power to change and over which he has no control.

حَتَّىٰ يَتَبَيَّنَ لَهُمْ أَنَّهُ الْحَقُّ ۗ أَوَلَمْ يَكْفِ بِرَبِّكَ أَنَّهُ عَلَىٰ كُلِّ شَيْءٍ شَهِيدٌ

(until it becomes manifest to them that this (the Qur'an) is the truth. Is it not sufficient in regard to your Lord that He is a Witness over all things?) means, sufficient is Allah as a Witness over the words and deeds of His servants, and He bears witness that Muhammad ﷺ is telling the truth in what he says, as Allah says:

لَٰكِنِ اللَّهُ يَشْهَدُ بِمَا أَنْزَلَ إِلَيْكَ ۖ أَنْزَلَهُ بِعِلْمِهِ ۖ 

(But Allah bears witness to that which He has sent down unto you; He has sent it down with His knowledge)(4:166).

أَلَا إِنَّهُمْ فِي مِرْيَةٍ مِنْ لِقَاءِ رَبِّهِمْ ۗ 

(Lo, Verily, they are in doubt concerning the meeting with their Lord.) means, they doubt that the Hour will come, they do not think about it or strive for it or pay heed to it; on the contrary, they regard it as irrelevant and do not care about it. But it will undoubtedly come to pass. Then Allah states that He is Able to do all things and He encompasses all things, and it is very easy for Him to bring about the Hour:

أَلَا إِنَّهُ بِكُلِّ شَيْءٍ مُحِيطٌ

(Verily, He is surrounding all things!) means, all of creation is subject to His control, dominion and knowledge; He is controlling all things by His power, so whatever He wills happens, and whatever He does not will does not happen, and there is no god worthy of worship apart from Him.

This is the end of the Tafsir of Surah Fussilat. To Allah be praise and blessings.
