The Quran root خ ل ف kh-l-f

وَقَالَتِ الْيَهُودُ لَيْسَتِ النَّصَارَىٰ عَلَىٰ شَيْءٍ وَقَالَتِ النَّصَارَىٰ لَيْسَتِ الْيَهُودُ عَلَىٰ شَيْءٍ وَهُمْ يَتْلُونَ الْكِتَابَ كَذَٰلِكَ قَالَ الَّذِينَ لَا يَعْلَمُونَ مِثْلَ قَوْلِهِمْ فَاللَّهُ يَحْكُمُ بَيْنَهُمْ يَوْمَ الْقِيَامَةِ فِيمَا كَانُوا فِيهِ يَخْتَلِفُونَ ١١٣

يَخْتَلِفُونَ yakhtalifūna · differing

The Jews say, "The Christians have nothing [true] to stand on," and the Christians say, "The Jews have nothing to stand on," although they [both] recite the Scripture. Thus do those who know not [i.e., the polytheists] speak the same as their words. But Allāh will judge between them on the Day of Resurrection concerning that over which they used to differ. (Surah Al-Baqarah, 2:113)

ذَٰلِكَ بِأَنَّ اللَّهَ نَزَّلَ الْكِتَابَ بِالْحَقِّ وَإِنَّ الَّذِينَ اخْتَلَفُوا فِي الْكِتَابِ لَفِي شِقَاقٍ بَعِيدٍ ١٧٦

اخْتَلَفُوا ikh'talafū · who differed

That is [deserved by them] because Allāh has sent down the Book in truth. And indeed, those who differ over the Book are in extreme dissension. (Surah Al-Baqarah, 2:176)

فَجَعَلْنَاهَا نَكَالًا لِّمَا بَيْنَ يَدَيْهَا وَمَا خَلْفَهَا وَمَوْعِظَةً لِّلْمُتَّقِينَ ٦٦

خَلْفَهَا khalfahā · after them

And We made it a deterrent punishment for those who were present and those who succeeded [them] and a lesson for those who fear Allāh. (Surah Al-Baqarah, 2:66)

وَقَالُوا لَن تَمَسَّنَا النَّارُ إِلَّا أَيَّامًا مَّعْدُودَةً قُلْ أَتَّخَذْتُمْ عِندَ اللَّهِ عَهْدًا فَلَن يُخْلِفَ اللَّهُ عَهْدَهُ أَمْ تَقُولُونَ عَلَى اللَّهِ مَا لَا تَعْلَمُونَ ٨٠

يُخْلِفَ yukh'lifa · will break

And they say, "Never will the Fire touch us, except for [a few] numbered days." Say, "Have you taken a covenant with Allāh? For Allāh will never break His covenant. Or do you say about Allāh that which you do not know?" (Surah Al-Baqarah, 2:80)

وَهُوَ الَّذِي أَنشَأَ جَنَّاتٍ مَّعْرُوشَاتٍ وَغَيْرَ مَعْرُوشَاتٍ وَالنَّخْلَ وَالزَّرْعَ مُخْتَلِفًا أُكُلُهُ وَالزَّيْتُونَ وَالرُّمَّانَ مُتَشَابِهًا وَغَيْرَ مُتَشَابِهٍ كُلُوا مِن ثَمَرِهِ إِذَا أَثْمَرَ وَآتُوا حَقَّهُ يَوْمَ حَصَادِهِ وَلَا تُسْرِفُوا إِنَّهُ لَا يُحِبُّ الْمُسْرِفِينَ ١٤١

مُخْتَلِفًا mukh'talifan · diverse

And He it is who causes gardens to grow, [both] trellised and untrellised, and palm trees and crops of different [kinds of] food and olives and pomegranates, similar and dissimilar. Eat of [each of] its fruit when it yields and give its due [zakāh] on the day of its harvest. And be not excessive. Indeed, He does not like those who commit excess. (Surah Al-An'am, 6:141)

وَإِذْ قَالَ رَبُّكَ لِلْمَلَائِكَةِ إِنِّي جَاعِلٌ فِي الْأَرْضِ خَلِيفَةً قَالُوا أَتَجْعَلُ فِيهَا مَن يُفْسِدُ فِيهَا وَيَسْفِكُ الدِّمَاءَ وَنَحْنُ نُسَبِّحُ بِحَمْدِكَ وَنُقَدِّسُ لَكَ قَالَ إِنِّي أَعْلَمُ مَا لَا تَعْلَمُونَ ٣٠

خَلِيفَةً khalīfatan · a vicegerent

And [mention, O Muḥammad], when your Lord said to the angels, "Indeed, I will make upon the earth a successive authority." They said, "Will You place upon it one who causes corruption therein and sheds blood, while we exalt You with praise and declare Your perfection?" He [Allāh] said, "Indeed, I know that which you do not know." (Surah Al-Baqarah, 2:30)
