لِيَكۡفُرُواْ بِمَآ ءَاتَيۡنَٰهُمۡ وَلِيَتَمَتَّعُواْۚ فَسَوۡفَ يَعۡلَمُونَ

Al-'Ankabut · 29:66Makkah

Saved, then ungrateful. They will come to know.

Enjoying the rescue while denying the Rescuer

After the rescue
savedbrought safe to land
turns into
ingratitudedenying what was given
enjoyment onlyfor a while
The end of the story
no one noticedlife goes on
they will knowthe gift is remembered

This completes the picture of the ship. Once safe, they denied what Allah gave them and went back to enjoying life as if nothing happened. The verse ends with a quiet warning: they are going to know.

You recovered from the illness. The debt got paid off. The family member came home safe. A month later you are complaining as if none of it happened. Gratitude is the proof that you understood who saved you.

That was a hard time, but it is over now.

It is over because of Allah. Remembering that is my thanks.

Tafsir Ibn Kathir (shared passage from 29:64)

And this life of the world is only an amusement and a play! Verily, the home of the Hereafter – that is the life indeed, if they but knew (64)And when they embark on a ship, they invoke Allah, making their faith pure for Him only, but when He brings them safely to land, behold, they give a share of their worship to others (65)So that they become ingrate for that which We have given them, and that they take their enjoyment, but they will come to know (66)

Allah tells us how insignificant and transient this world is, and how it will soon end. All that it is, is amusement and play:

وَإِنَّ الدَّارَ الْآخِرَةَ لَهِيَ الْحَيَوَانُ ۚ 

(Verily, the home of the Hereafter – that is the life indeed,) means, the true everlasting life that will never end, but will continue forever and ever.

لَوْ كَانُوا يَعْلَمُونَ

(if they but knew.) means, they would prefer that which will last over that which will pass away. Then Allah says that at times of calamity, the idolators call upon Him alone, with no partner or associate, so why do they not do that all the time?

فَإِذَا رَكِبُوا فِي الْفُلْكِ دَعَوُا اللَّهَ مُخْلِصِينَ لَهُ الدِّينَ 

(And when they embark on a ship, they invoke Allah, making their faith pure for Him only,) This is like the Ayah,

وَإِذَا مَسَّكُمُ الضُّرُّ فِي الْبَحْرِ ضَلَّ مَنْ تَدْعُونَ إِلَّا إِيَّاهُ ۖ فَلَمَّا نَجَّاكُمْ إِلَى الْبَرِّ أَعْرَضْتُمْ ۚ 

(And when harm touches you upon the sea, those that you call upon vanish from you except Him (Allah Alone). But when He brings you safely to land, you turn away)(17:67). Allah says here:

 فَلَمَّا نَجَّاهُمْ إِلَى الْبَرِّ إِذَا هُمْ يُشْرِكُونَ

(but when He brings them safely to land, behold, they give a share of their worship to others.)

Muhammad bin Ishaq reported from 'Ikrimah bin Abi Jahl that when the Messenger of Allah ﷺ conquered Makkah, he ('Ikrimah) ran away, fleeing from him. When he was on the sea, headed for Ethiopia, the ship started to rock and the crew said: "O people, pray sincerely to your Lord alone, for no one can save us from this except Him." 'Ikrimah said: "By Allah, if there is none who can save us on the sea except Him, then there is none who can save us on land except Him either, O Allah, I vow to You that if I come out of this, I will go and put my hand in the hand of Muhammad and I will find him kind and merciful." And this is what indeed did happen.

لِيَكْفُرُوا بِمَا آتَيْنَاهُمْ وَلِيَتَمَتَّعُوا ۖ 

(So that they become ingrate for that which We have given them, and that they take their enjoyment,)
