The word ثبت in the Quran

وَلَمَّا بَرَزُوا۟ لِجَالُوتَ وَجُنُودِهِۦ قَالُوا۟ رَبَّنَآ أَفْرِغْ عَلَيْنَا صَبْرًا وَثَبِّتْ أَقْدَامَنَا وَٱنصُرْنَا عَلَى ٱلْقَوْمِ ٱلْكَٰفِرِينَ ۝٢٥٠

And when they went forth to [face] Goliath and his soldiers, they said, "Our Lord, pour upon us patience and plant firmly our feet and give us victory over the disbelieving people."

وَمَا كَانَ قَوْلَهُمْ إِلَّآ أَن قَالُوا۟ رَبَّنَا ٱغْفِرْ لَنَا ذُنُوبَنَا وَإِسْرَافَنَا فِىٓ أَمْرِنَا وَثَبِّتْ أَقْدَامَنَا وَٱنصُرْنَا عَلَى ٱلْقَوْمِ ٱلْكَٰفِرِينَ ۝١٤٧

And their words were not but that they said, "Our Lord, forgive us our sins and the excess [committed] in our affairs and plant firmly our feet and give us victory over the disbelieving people."

إِذْ يُغَشِّيكُمُ ٱلنُّعَاسَ أَمَنَةً مِّنْهُ وَيُنَزِّلُ عَلَيْكُم مِّنَ ٱلسَّمَآءِ مَآءً لِّيُطَهِّرَكُم بِهِۦ وَيُذْهِبَ عَنكُمْ رِجْزَ ٱلشَّيْطَٰنِ وَلِيَرْبِطَ عَلَىٰ قُلُوبِكُمْ وَيُثَبِّتَ بِهِ ٱلْأَقْدَامَ ۝١١

[Remember] when He overwhelmed you with drowsiness [giving] security from Him and sent down upon you from the sky, rain by which to purify you and remove from you the evil [suggestions] of Satan and to make steadfast your hearts and plant firmly thereby your feet.

إِذْ يُوحِى رَبُّكَ إِلَى ٱلْمَلَٰٓئِكَةِ أَنِّى مَعَكُمْ فَثَبِّتُوا۟ ٱلَّذِينَ ءَامَنُوا۟ سَأُلْقِى فِى قُلُوبِ ٱلَّذِينَ كَفَرُوا۟ ٱلرُّعْبَ فَٱضْرِبُوا۟ فَوْقَ ٱلْأَعْنَاقِ وَٱضْرِبُوا۟ مِنْهُمْ كُلَّ بَنَانٍ ۝١٢

[Remember] when your Lord inspired to the angels, "I am with you, so strengthen those who have believed. I will cast terror into the hearts of those who disbelieved, so strike [them] upon the necks and strike from them every fingertip."

وَكُلًّا نَّقُصُّ عَلَيْكَ مِنْ أَنۢبَآءِ ٱلرُّسُلِ مَا نُثَبِّتُ بِهِۦ فُؤَادَكَ وَجَآءَكَ فِى هَٰذِهِ ٱلْحَقُّ وَمَوْعِظَةٌ وَذِكْرَىٰ لِلْمُؤْمِنِينَ ۝١٢٠

And each [story] We relate to you from the news of the messengers is that by which We make firm your heart. And there has come to you, in this, the truth and an instruction and a reminder for the believers.

يُثَبِّتُ ٱللَّهُ ٱلَّذِينَ ءَامَنُوا۟ بِٱلْقَوْلِ ٱلثَّابِتِ فِى ٱلْحَيَوٰةِ ٱلدُّنْيَا وَفِى ٱلْـَٔاخِرَةِ وَيُضِلُّ ٱللَّهُ ٱلظَّٰلِمِينَ وَيَفْعَلُ ٱللَّهُ مَا يَشَآءُ ۝٢٧

Allāh keeps firm those who believe, with the firm word, in worldly life and in the Hereafter. And Allāh sends astray the wrongdoers. And Allāh does what He wills.

قُلْ نَزَّلَهُۥ رُوحُ ٱلْقُدُسِ مِن رَّبِّكَ بِٱلْحَقِّ لِيُثَبِّتَ ٱلَّذِينَ ءَامَنُوا۟ وَهُدًى وَبُشْرَىٰ لِلْمُسْلِمِينَ ۝١٠٢

Say, [O Muḥammad], "The Pure Spirit [i.e., Gabriel] has brought it down from your Lord in truth to make firm those who believe and as guidance and good tidings to the Muslims."

وَلَوْلَآ أَن ثَبَّتْنَٰكَ لَقَدْ كِدتَّ تَرْكَنُ إِلَيْهِمْ شَيْـًٔا قَلِيلًا ۝٧٤

And if We had not strengthened you, you would have almost inclined to them a little.

وَقَالَ ٱلَّذِينَ كَفَرُوا۟ لَوْلَا نُزِّلَ عَلَيْهِ ٱلْقُرْءَانُ جُمْلَةً وَٰحِدَةً كَذَٰلِكَ لِنُثَبِّتَ بِهِۦ فُؤَادَكَ وَرَتَّلْنَٰهُ تَرْتِيلًا ۝٣٢

And those who disbelieve say, "Why was the Qur’ān not revealed to him all at once?" Thus [it is] that We may strengthen thereby your heart. And We have spaced it distinctly.

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِن تَنصُرُوا۟ ٱللَّهَ يَنصُرْكُمْ وَيُثَبِّتْ أَقْدَامَكُمْ ۝٧

O you who have believed, if you support Allāh, He will support you and plant firmly your feet.
