The Quran root ص ف و ṣ-f-w

وَمَن يَرْغَبُ عَن مِّلَّةِ إِبْرَاهِيمَ إِلَّا مَن سَفِهَ نَفْسَهُ وَلَقَدِ اصْطَفَيْنَاهُ فِي الدُّنْيَا وَإِنَّهُ فِي الْآخِرَةِ لَمِنَ الصَّالِحِينَ ١٣٠

اصْطَفَيْنَاهُ iṣ'ṭafaynāhu · We chose him

And who would be averse to the religion of Abraham except one who makes a fool of himself. And We had chosen him in this world, and indeed he, in the Hereafter, will be among the righteous. (Surah Al-Baqarah, 2:130)

وَوَصَّىٰ بِهَا إِبْرَاهِيمُ بَنِيهِ وَيَعْقُوبُ يَا بَنِيَّ إِنَّ اللَّهَ اصْطَفَىٰ لَكُمُ الدِّينَ فَلَا تَمُوتُنَّ إِلَّا وَأَنتُم مُّسْلِمُونَ ١٣٢

اصْطَفَىٰ iṣ'ṭafā · has chosen

And Abraham instructed his sons [to do the same] and [so did] Jacob, [saying], "O my sons, indeed Allāh has chosen for you this religion, so do not die except while you are Muslims." (Surah Al-Baqarah, 2:132)

أَفَأَصْفَاكُمْ رَبُّكُم بِالْبَنِينَ وَاتَّخَذَ مِنَ الْمَلَائِكَةِ إِنَاثًا إِنَّكُمْ لَتَقُولُونَ قَوْلًا عَظِيمًا ٤٠

أَفَأَصْفَاكُمْ afa-aṣfākum · Then has your Lord chosen (for) you

Then, has your Lord chosen you for [having] sons and taken [i.e., adopted] from among the angels daughters? Indeed, you say a grave saying. (Surah Al-Isra, 17:40)

يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تُبْطِلُوا صَدَقَاتِكُم بِالْمَنِّ وَالْأَذَىٰ كَالَّذِي يُنفِقُ مَالَهُ رِئَاءَ النَّاسِ وَلَا يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ فَمَثَلُهُ كَمَثَلِ صَفْوَانٍ عَلَيْهِ تُرَابٌ فَأَصَابَهُ وَابِلٌ فَتَرَكَهُ صَلْدًا لَّا يَقْدِرُونَ عَلَىٰ شَيْءٍ مِّمَّا كَسَبُوا وَاللَّهُ لَا يَهْدِي الْقَوْمَ الْكَافِرِينَ ٢٦٤

صَفْوَانٍ ṣafwānin · (that of a) smooth rock

O you who have believed, do not invalidate your charities with reminders [of it] or injury as does one who spends his wealth [only] to be seen by the people and does not believe in Allāh and the Last Day. His example is like that of a [large] smooth stone upon which is dust and is hit by a downpour that leaves it bare. They are unable [to keep] anything of what they have earned. And Allāh does not guide the disbelieving people. (Surah Al-Baqarah, 2:264)

وَإِنَّهُمْ عِندَنَا لَمِنَ الْمُصْطَفَيْنَ الْأَخْيَارِ ٤٧

الْمُصْطَفَيْنَ l-muṣ'ṭafayna · the chosen ones

And indeed they are, to Us, among the chosen and outstanding. (Surah Sad, 38:47)

مَّثَلُ الْجَنَّةِ الَّتِي وُعِدَ الْمُتَّقُونَ فِيهَا أَنْهَارٌ مِّن مَّاءٍ غَيْرِ آسِنٍ وَأَنْهَارٌ مِّن لَّبَنٍ لَّمْ يَتَغَيَّرْ طَعْمُهُ وَأَنْهَارٌ مِّنْ خَمْرٍ لَّذَّةٍ لِّلشَّارِبِينَ وَأَنْهَارٌ مِّنْ عَسَلٍ مُّصَفًّى وَلَهُمْ فِيهَا مِن كُلِّ الثَّمَرَاتِ وَمَغْفِرَةٌ مِّن رَّبِّهِمْ كَمَنْ هُوَ خَالِدٌ فِي النَّارِ وَسُقُوا مَاءً حَمِيمًا فَقَطَّعَ أَمْعَاءَهُمْ ١٥

مُّصَفًّى muṣaffan · purified

Is the description of Paradise, which the righteous are promised, wherein are rivers of water unaltered, rivers of milk the taste of which never changes, rivers of wine delicious to those who drink, and rivers of purified honey, in which they will have from all [kinds of] fruits and forgiveness from their Lord... [Are its inhabitants] like those who abide eternally in the Fire and are given to drink scalding water that will sever their intestines? (Surah Muhammad, 47:15)
