وَإِذَا لَقُوا الَّذِينَ آمَنُوا قَالُوا آمَنَّا وَإِذَا خَلَا بَعْضُهُمْ إِلَىٰ بَعْضٍ قَالُوا أَتُحَدِّثُونَهُم بِمَا فَتَحَ اللَّهُ عَلَيْكُمْ لِيُحَاجُّوكُم بِهِ عِندَ رَبِّكُمْ أَفَلَا تَعْقِلُونَ ٧٦

فَتَحَ fataḥa · has

And when they meet those who believe, they say, "We have believed"; but when they are alone with one another, they say, "Do you talk to them about what Allāh has revealed to you so they can argue with you about it before your Lord?" Then will you not reason? (Surah Al-Baqarah, 2:76)

فَلَمَّا نَسُوا مَا ذُكِّرُوا بِهِ فَتَحْنَا عَلَيْهِمْ أَبْوَابَ كُلِّ شَيْءٍ حَتَّىٰ إِذَا فَرِحُوا بِمَا أُوتُوا أَخَذْنَاهُم بَغْتَةً فَإِذَا هُم مُّبْلِسُونَ ٤٤

فَتَحْنَا fataḥnā · We opened

So when they forgot that by which they had been reminded, We opened to them the doors of every [good] thing until, when they rejoiced in that which they were given, We seized them suddenly, and they were [then] in despair. (Surah Al-An'am, 6:44)

الَّذِينَ يَتَرَبَّصُونَ بِكُمْ فَإِن كَانَ لَكُمْ فَتْحٌ مِّنَ اللَّهِ قَالُوا أَلَمْ نَكُن مَّعَكُمْ وَإِن كَانَ لِلْكَافِرِينَ نَصِيبٌ قَالُوا أَلَمْ نَسْتَحْوِذْ عَلَيْكُمْ وَنَمْنَعْكُم مِّنَ الْمُؤْمِنِينَ فَاللَّهُ يَحْكُمُ بَيْنَكُمْ يَوْمَ الْقِيَامَةِ وَلَن يَجْعَلَ اللَّهُ لِلْكَافِرِينَ عَلَى الْمُؤْمِنِينَ سَبِيلًا ١٤١

فَتْحٌ fatḥun · a victory

Those who wait [and watch] you. Then if you gain a victory from Allāh, they say, "Were we not with you?" But if the disbelievers have a success, they say [to them], "Did we not gain the advantage over you, but we protected you from the believers?" Allāh will judge between [all of] you on the Day of Resurrection, and never will Allāh give the disbelievers over the believers a way [to overcome them]. (Surah An-Nisa, 4:141)

وَلَمَّا جَاءَهُمْ كِتَابٌ مِّنْ عِندِ اللَّهِ مُصَدِّقٌ لِّمَا مَعَهُمْ وَكَانُوا مِن قَبْلُ يَسْتَفْتِحُونَ عَلَى الَّذِينَ كَفَرُوا فَلَمَّا جَاءَهُم مَّا عَرَفُوا كَفَرُوا بِهِ فَلَعْنَةُ اللَّهِ عَلَى الْكَافِرِينَ ٨٩

يَسْتَفْتِحُونَ yastaftiḥūna · (that), pray for victory

And when there came to them a Book [i.e., the Qur’ān] from Allāh confirming that which was with them - although before they used to pray for victory against those who disbelieved - but [then] when there came to them that which they recognized, they disbelieved in it; so the curse of Allāh will be upon the disbelievers. (Surah Al-Baqarah, 2:89)

وَعِندَهُ مَفَاتِحُ الْغَيْبِ لَا يَعْلَمُهَا إِلَّا هُوَ وَيَعْلَمُ مَا فِي الْبَرِّ وَالْبَحْرِ وَمَا تَسْقُطُ مِن وَرَقَةٍ إِلَّا يَعْلَمُهَا وَلَا حَبَّةٍ فِي ظُلُمَاتِ الْأَرْضِ وَلَا رَطْبٍ وَلَا يَابِسٍ إِلَّا فِي كِتَابٍ مُّبِينٍ ٥٩

مَفَاتِحُ mafātiḥu · (are the) keys

And with Him are the keys of the unseen; none knows them except Him. And He knows what is on the land and in the sea. Not a leaf falls but that He knows it. And no grain is there within the darknesses of the earth and no moist or dry [thing] but that it is [written] in a clear record. (Surah Al-An'am, 6:59)

إِنَّ الَّذِينَ كَذَّبُوا بِآيَاتِنَا وَاسْتَكْبَرُوا عَنْهَا لَا تُفَتَّحُ لَهُمْ أَبْوَابُ السَّمَاءِ وَلَا يَدْخُلُونَ الْجَنَّةَ حَتَّىٰ يَلِجَ الْجَمَلُ فِي سَمِّ الْخِيَاطِ وَكَذَٰلِكَ نَجْزِي الْمُجْرِمِينَ ٤٠

تُفَتَّحُ tufattaḥu · be opened

Indeed, those who deny Our verses and are arrogant toward them - the gates of Heaven will not be opened for them, nor will they enter Paradise until a camel enters into the eye of a needle [i.e., never]. And thus do We recompense the criminals. (Surah Al-A'raf, 7:40)
