وَالصَّاحِبِ wal-ṣāḥibi · and the companion

Worship Allāh and associate nothing with Him, and to parents do good, and to relatives, orphans, the needy, the near neighbor, the neighbor farther away, the companion at your side, the traveler, and those whom your right hands possess. Indeed, Allāh does not like those who are self-deluding and boastful, (Surah An-Nisa, 4:36)

بَدِيعُ السَّمَاوَاتِ وَالْأَرْضِ أَنَّىٰ يَكُونُ لَهُ وَلَدٌ وَلَمْ تَكُن لَّهُ صَاحِبَةٌ وَخَلَقَ كُلَّ شَيْءٍ وَهُوَ بِكُلِّ شَيْءٍ عَلِيمٌ ١٠١

صَاحِبَةٌ ṣāḥibatun · a companion

قَالَ إِن سَأَلْتُكَ عَن شَيْءٍ بَعْدَهَا فَلَا تُصَاحِبْنِي قَدْ بَلَغْتَ مِن لَّدُنِّي عُذْرًا ٧٦
