الرِّقَابِ l-riqābi · freeing the necks (slaves)

Righteousness is not that you turn your faces toward the east or the west, but [true] righteousness is [in] one who believes in Allāh, the Last Day, the angels, the Book, and the prophets and gives wealth, in spite of love for it, to relatives, orphans, the needy, the traveler, those who ask [for help], and for freeing slaves; [and who] establishes prayer and gives zakāh; [those who] fulfill their promise when they promise; and [those who] are patient in poverty and hardship and during battle. Those are the ones who have been true, and it is those who are the righteous. (Surah Al-Baqarah, 2:177)

وَمَا كَانَ لِمُؤْمِنٍ أَن يَقْتُلَ مُؤْمِنًا إِلَّا خَطَأً وَمَن قَتَلَ مُؤْمِنًا خَطَأً فَتَحْرِيرُ رَقَبَةٍ مُّؤْمِنَةٍ وَدِيَةٌ مُّسَلَّمَةٌ إِلَىٰ أَهْلِهِ إِلَّا أَن يَصَّدَّقُوا فَإِن كَانَ مِن قَوْمٍ عَدُوٍّ لَّكُمْ وَهُوَ مُؤْمِنٌ فَتَحْرِيرُ رَقَبَةٍ مُّؤْمِنَةٍ وَإِن كَانَ مِن قَوْمٍ بَيْنَكُمْ وَبَيْنَهُم مِّيثَاقٌ فَدِيَةٌ مُّسَلَّمَةٌ إِلَىٰ أَهْلِهِ وَتَحْرِيرُ رَقَبَةٍ مُّؤْمِنَةٍ فَمَن لَّمْ يَجِدْ فَصِيَامُ شَهْرَيْنِ مُتَتَابِعَيْنِ تَوْبَةً مِّنَ اللَّهِ وَكَانَ اللَّهُ عَلِيمًا حَكِيمًا ٩٢

رَقَبَةٍ raqabatin · (of) a slave

And never is it for a believer to kill a believer except by mistake. And whoever kills a believer by mistake - then the freeing of a believing slave and a compensation payment [diyah] presented to his [i.e., the deceased's] family [is required], unless they give [up their right as] charity. But if he [i.e., the deceased] was from a people at war with you and he was a believer - then [only] the freeing of a believing slave; and if he was from a people with whom you have a treaty - then a compensation payment presented to his family and the freeing of a believing slave. And whoever does not find [one or cannot afford to buy one] - then [instead], a fast for two months consecutively, [seeking] acceptance of repentance from Allāh. And Allāh is ever Knowing and Wise. (Surah An-Nisa, 4:92)

يَا أَيُّهَا النَّاسُ اتَّقُوا رَبَّكُمُ الَّذِي خَلَقَكُم مِّن نَّفْسٍ وَاحِدَةٍ وَخَلَقَ مِنْهَا زَوْجَهَا وَبَثَّ مِنْهُمَا رِجَالًا كَثِيرًا وَنِسَاءً وَاتَّقُوا اللَّهَ الَّذِي تَسَاءَلُونَ بِهِ وَالْأَرْحَامَ إِنَّ اللَّهَ كَانَ عَلَيْكُمْ رَقِيبًا ١

رَقِيبًا raqīban · Ever-Watchful

O mankind, fear your Lord, who created you from one soul and created from it its mate and dispersed from both of them many men and women. And fear Allāh, through whom you ask one another, and the wombs. Indeed Allāh is ever, over you, an Observer. (Surah An-Nisa, 4:1)

وَيَا قَوْمِ اعْمَلُوا عَلَىٰ مَكَانَتِكُمْ إِنِّي عَامِلٌ سَوْفَ تَعْلَمُونَ مَن يَأْتِيهِ عَذَابٌ يُخْزِيهِ وَمَنْ هُوَ كَاذِبٌ وَارْتَقِبُوا إِنِّي مَعَكُمْ رَقِيبٌ ٩٣

وَارْتَقِبُوا wa-ir'taqibū · And watch

And O my people, work according to your position; indeed, I am working. You are going to know to whom will come a punishment that will disgrace him and who is a liar. So watch; indeed, I am with you a watcher, [awaiting the outcome]." (Surah Hud, 11:93)

كَيْفَ وَإِن يَظْهَرُوا عَلَيْكُمْ لَا يَرْقُبُوا فِيكُمْ إِلًّا وَلَا ذِمَّةً يُرْضُونَكُم بِأَفْوَاهِهِمْ وَتَأْبَىٰ قُلُوبُهُمْ وَأَكْثَرُهُمْ فَاسِقُونَ ٨

يَرْقُبُوا yarqubū · they do not regard (the ties)

How [can there be a treaty] while, if they gain dominance over you, they do not observe concerning you any pact of kinship or covenant of protection? They satisfy you with their mouths, but their hearts refuse [compliance], and most of them are defiantly disobedient. (Surah At-Tawbah, 9:8)

فَأَصْبَحَ فِي الْمَدِينَةِ خَائِفًا يَتَرَقَّبُ فَإِذَا الَّذِي اسْتَنصَرَهُ بِالْأَمْسِ يَسْتَصْرِخُهُ قَالَ لَهُ مُوسَىٰ إِنَّكَ لَغَوِيٌّ مُّبِينٌ ١٨

يَتَرَقَّبُ yataraqqabu · (and) was vigilant

And he became inside the city fearful and anticipating [exposure], when suddenly the one who sought his help the previous day cried out to him [once again]. Moses said to him, "Indeed, you are an evident, [persistent] deviator." (Surah Al-Qasas, 28:18)
