The word آن in the Quran

قَالَ إِنَّهُۥ يَقُولُ إِنَّهَا بَقَرَةٌ لَّا ذَلُولٌ تُثِيرُ ٱلْأَرْضَ وَلَا تَسْقِى ٱلْحَرْثَ مُسَلَّمَةٌ لَّا شِيَةَ فِيهَا قَالُوا۟ ٱلْـَٰٔنَ جِئْتَ بِٱلْحَقِّ فَذَبَحُوهَا وَمَا كَادُوا۟ يَفْعَلُونَ ۝٧١

He said, "He says, 'It is a cow neither trained to plow the earth nor to irrigate the field, one free from fault with no spot upon her.'" They said, "Now you have come with the truth." So they slaughtered her, but they could hardly do it.

أُحِلَّ لَكُمْ لَيْلَةَ ٱلصِّيَامِ ٱلرَّفَثُ إِلَىٰ نِسَآئِكُمْ هُنَّ لِبَاسٌ لَّكُمْ وَأَنتُمْ لِبَاسٌ لَّهُنَّ عَلِمَ ٱللَّهُ أَنَّكُمْ كُنتُمْ تَخْتَانُونَ أَنفُسَكُمْ فَتَابَ عَلَيْكُمْ وَعَفَا عَنكُمْ فَٱلْـَٰٔنَ بَٰشِرُوهُنَّ وَٱبْتَغُوا۟ مَا كَتَبَ ٱللَّهُ لَكُمْ وَكُلُوا۟ وَٱشْرَبُوا۟ حَتَّىٰ يَتَبَيَّنَ لَكُمُ ٱلْخَيْطُ ٱلْأَبْيَضُ مِنَ ٱلْخَيْطِ ٱلْأَسْوَدِ مِنَ ٱلْفَجْرِ ثُمَّ أَتِمُّوا۟ ٱلصِّيَامَ إِلَى ٱلَّيْلِ وَلَا تُبَٰشِرُوهُنَّ وَأَنتُمْ عَٰكِفُونَ فِى ٱلْمَسَٰجِدِ تِلْكَ حُدُودُ ٱللَّهِ فَلَا تَقْرَبُوهَا كَذَٰلِكَ يُبَيِّنُ ٱللَّهُ ءَايَٰتِهِۦ لِلنَّاسِ لَعَلَّهُمْ يَتَّقُونَ ۝١٨٧

It has been made permissible for you the night preceding fasting to go to your wives [for sexual relations]. They are a clothing for you and you are a clothing for them. Allāh knows that you used to deceive yourselves, so He accepted your repentance and forgave you. So now, have relations with them and seek that which Allāh has decreed for you [i.e., offspring]. And eat and drink until the white thread of dawn becomes distinct to you from the black thread [of night]. Then complete the fast until the night [i.e., sunset]. And do not have relations with them as long as you are staying for worship in the mosques. These are the limits [set by] Allāh, so do not approach them. Thus does Allāh make clear His verses [i.e., ordinances] to the people that they may become righteous.

وَلَيْسَتِ ٱلتَّوْبَةُ لِلَّذِينَ يَعْمَلُونَ ٱلسَّيِّـَٔاتِ حَتَّىٰٓ إِذَا حَضَرَ أَحَدَهُمُ ٱلْمَوْتُ قَالَ إِنِّى تُبْتُ ٱلْـَٰٔنَ وَلَا ٱلَّذِينَ يَمُوتُونَ وَهُمْ كُفَّارٌ أُو۟لَٰٓئِكَ أَعْتَدْنَا لَهُمْ عَذَابًا أَلِيمًا ۝١٨

But repentance is not [accepted] of those who [continue to] do evil deeds up until, when death comes to one of them, he says, "Indeed, I have repented now," or of those who die while they are disbelievers. For them We have prepared a painful punishment.

ٱلْـَٰٔنَ خَفَّفَ ٱللَّهُ عَنكُمْ وَعَلِمَ أَنَّ فِيكُمْ ضَعْفًا فَإِن يَكُن مِّنكُم مِّا۟ئَةٌ صَابِرَةٌ يَغْلِبُوا۟ مِا۟ئَتَيْنِ وَإِن يَكُن مِّنكُمْ أَلْفٌ يَغْلِبُوٓا۟ أَلْفَيْنِ بِإِذْنِ ٱللَّهِ وَٱللَّهُ مَعَ ٱلصَّٰبِرِينَ ۝٦٦

Now, Allāh has lightened [the hardship] for you, and He knows that among you is weakness. So if there are from you one hundred [who are] steadfast, they will overcome two hundred. And if there are among you a thousand, they will overcome two thousand by permission of Allāh. And Allāh is with the steadfast.

أَثُمَّ إِذَا مَا وَقَعَ ءَامَنتُم بِهِۦٓ ءَآلْـَٰٔنَ وَقَدْ كُنتُم بِهِۦ تَسْتَعْجِلُونَ ۝٥١

Then is it that when it has [actually] occurred you will believe in it? Now? And you were [once] for it impatient.

ءَآلْـَٰٔنَ وَقَدْ عَصَيْتَ قَبْلُ وَكُنتَ مِنَ ٱلْمُفْسِدِينَ ۝٩١

Now? And you had disobeyed [Him] before and were of the corrupters?

قَالَ مَا خَطْبُكُنَّ إِذْ رَٰوَدتُّنَّ يُوسُفَ عَن نَّفْسِهِۦ قُلْنَ حَٰشَ لِلَّهِ مَا عَلِمْنَا عَلَيْهِ مِن سُوٓءٍ قَالَتِ ٱمْرَأَتُ ٱلْعَزِيزِ ٱلْـَٰٔنَ حَصْحَصَ ٱلْحَقُّ أَنَا۠ رَٰوَدتُّهُۥ عَن نَّفْسِهِۦ وَإِنَّهُۥ لَمِنَ ٱلصَّٰدِقِينَ ۝٥١

Said [the king to the women], "What was your condition when you sought to seduce Joseph?" They said, "Perfect is Allāh! We know about him no evil." The wife of al-ʿAzeez said, "Now the truth has become evident. It was I who sought to seduce him, and indeed, he is of the truthful.

يَطُوفُونَ بَيْنَهَا وَبَيْنَ حَمِيمٍ ءَانٍ ۝٤٤

They will circulate between it and scalding water, heated [to the utmost degree].

وَأَنَّا كُنَّا نَقْعُدُ مِنْهَا مَقَٰعِدَ لِلسَّمْعِ فَمَن يَسْتَمِعِ ٱلْـَٔانَ يَجِدْ لَهُۥ شِهَابًا رَّصَدًا ۝٩

And we used to sit therein in positions for hearing, but whoever listens now will find a burning flame lying in wait for him.
