رَيْبٍ raybin · doubt

And if you are in doubt about what We have sent down [i.e., the Qur’ān] upon Our Servant [i.e., Prophet Muḥammad (ﷺ)], then produce a sūrah the like thereof and call upon your witnesses [i.e., supporters] other than Allāh, if you should be truthful. (Surah Al-Baqarah, 2:23)

يَا أَيُّهَا الَّذِينَ آمَنُوا إِذَا تَدَايَنتُم بِدَيْنٍ إِلَىٰ أَجَلٍ مُّسَمًّى فَاكْتُبُوهُ وَلْيَكْتُب بَّيْنَكُمْ كَاتِبٌ بِالْعَدْلِ وَلَا يَأْبَ كَاتِبٌ أَن يَكْتُبَ كَمَا عَلَّمَهُ اللَّهُ فَلْيَكْتُبْ وَلْيُمْلِلِ الَّذِي عَلَيْهِ الْحَقُّ وَلْيَتَّقِ اللَّهَ رَبَّهُ وَلَا يَبْخَسْ مِنْهُ شَيْئًا فَإِن كَانَ الَّذِي عَلَيْهِ الْحَقُّ سَفِيهًا أَوْ ضَعِيفًا أَوْ لَا يَسْتَطِيعُ أَن يُمِلَّ هُوَ فَلْيُمْلِلْ وَلِيُّهُ بِالْعَدْلِ وَاسْتَشْهِدُوا شَهِيدَيْنِ مِن رِّجَالِكُمْ فَإِن لَّمْ يَكُونَا رَجُلَيْنِ فَرَجُلٌ وَامْرَأَتَانِ مِمَّن تَرْضَوْنَ مِنَ الشُّهَدَاءِ أَن تَضِلَّ إِحْدَاهُمَا فَتُذَكِّرَ إِحْدَاهُمَا الْأُخْرَىٰ وَلَا يَأْبَ الشُّهَدَاءُ إِذَا مَا دُعُوا وَلَا تَسْأَمُوا أَن تَكْتُبُوهُ صَغِيرًا أَوْ كَبِيرًا إِلَىٰ أَجَلِهِ ذَٰلِكُمْ أَقْسَطُ عِندَ اللَّهِ وَأَقْوَمُ لِلشَّهَادَةِ وَأَدْنَىٰ أَلَّا تَرْتَابُوا إِلَّا أَن تَكُونَ تِجَارَةً حَاضِرَةً تُدِيرُونَهَا بَيْنَكُمْ فَلَيْسَ عَلَيْكُمْ جُنَاحٌ أَلَّا تَكْتُبُوهَا وَأَشْهِدُوا إِذَا تَبَايَعْتُمْ وَلَا يُضَارَّ كَاتِبٌ وَلَا شَهِيدٌ وَإِن تَفْعَلُوا فَإِنَّهُ فُسُوقٌ بِكُمْ وَاتَّقُوا اللَّهَ وَيُعَلِّمُكُمُ اللَّهُ وَاللَّهُ بِكُلِّ شَيْءٍ عَلِيمٌ ٢٨٢

تَرْتَابُوا tartābū · you (have) doubt

O you who have believed, when you contract a debt for a specified term, write it down. And let a scribe write [it] between you in justice. Let no scribe refuse to write as Allāh has taught him. So let him write and let the one who has the obligation [i.e., the debtor] dictate. And let him fear Allāh, his Lord, and not leave anything out of it. But if the one who has the obligation is of limited understanding or weak or unable to dictate himself, then let his guardian dictate in justice. And bring to witness two witnesses from among your men. And if there are not two men [available], then a man and two women from those whom you accept as witnesses - so that if one of them [i.e., the women] errs, then the other can remind her. And let not the witnesses refuse when they are called upon. And do not be [too] weary to write it, whether it is small or large, for its [specified] term. That is more just in the sight of Allāh and stronger as evidence and more likely to prevent doubt between you, except when it is an immediate transaction which you conduct among yourselves. For [then] there is no blame upon you if you do not write it. And take witnesses when you conclude a contract. Let no scribe be harmed or any witness. For if you do so, indeed, it is [grave] disobedience in you. And fear Allāh. And Allāh teaches you. And Allāh is Knowing of all things. (Surah Al-Baqarah, 2:282)

قَالُوا يَا صَالِحُ قَدْ كُنتَ فِينَا مَرْجُوًّا قَبْلَ هَٰذَا أَتَنْهَانَا أَن نَّعْبُدَ مَا يَعْبُدُ آبَاؤُنَا وَإِنَّنَا لَفِي شَكٍّ مِّمَّا تَدْعُونَا إِلَيْهِ مُرِيبٍ ٦٢

مُرِيبٍ murībin · suspicious

They said, "O Ṣāliḥ, you were among us a man of promise before this. Do you forbid us to worship what our fathers worshipped? And indeed we are, about that to which you invite us, in disquieting doubt." (Surah Hud, 11:62)

لَا يَزَالُ بُنْيَانُهُمُ الَّذِي بَنَوْا رِيبَةً فِي قُلُوبِهِمْ إِلَّا أَن تَقَطَّعَ قُلُوبُهُمْ وَاللَّهُ عَلِيمٌ حَكِيمٌ ١١٠

رِيبَةً rībatan · a (cause of) doubt

Their building which they built will not cease to be a [cause of] skepticism in their hearts until their hearts are cut [i.e., stopped]. And Allāh is Knowing and Wise. (Surah At-Tawbah, 9:110)

وَلَقَدْ جَاءَكُمْ يُوسُفُ مِن قَبْلُ بِالْبَيِّنَاتِ فَمَا زِلْتُمْ فِي شَكٍّ مِّمَّا جَاءَكُم بِهِ حَتَّىٰ إِذَا هَلَكَ قُلْتُمْ لَن يَبْعَثَ اللَّهُ مِن بَعْدِهِ رَسُولًا كَذَٰلِكَ يُضِلُّ اللَّهُ مَنْ هُوَ مُسْرِفٌ مُّرْتَابٌ ٣٤

مُّرْتَابٌ mur'tābun · a doubter

And Joseph had already come to you before with clear proofs, but you remained in doubt of that which he brought to you, until when he died, you said, 'Never will Allāh send a messenger after him.' Thus does Allāh leave astray he who is a transgressor and skeptic." (Surah Ghafir, 40:34)
