Qurʾān Bukhārī Muslim Nasāʾī Abū Dāwūd Tirmidhī Ibn Mājah Mālik Aḥmad Dārimī Ḥākim Ibn Ḥibbān Ṭabarānī Nasāʾī's Kubrá Bayhaqī al-Luʾluʾ wa-al-Marjān Ibn Rajab's Fifty Riyāḍ al-Ṣāliḥīn Aḥmad's Zuhd Suyūṭī
quran:15:47 –

And We will remove whatever is in their breasts of resentment, ˹so they will be˺ brothers, on thrones facing each other.  

And We remove whatever rancour, spite, may be in their breasts. As brethren (ikhwānan is a circumstantial qualifier referring to them), ˹they shall recline˺ upon couches, facing one another (mutaqābilīn is also a circumstantial qualifier), in other words, they do not look upon each other’s backs, because the couches revolve with them in them.
القرآن:١٥:٤٧ –

وَنَزَعْنَا مَا فِي صُدُورِهِمْ مِنْ غِلٍّ إِخْوَانًا عَلَىٰ سُرُرٍ مُتَقَابِلِينَ  

{ونزعنا ما في صدورهم من غِلِّ} حقد {إخوانا} حال منهم {على سُرر متقابلين} حال أيضا أي لا ينظر بعضهم إلى قفا بعض لدورات الأسرَّة بهم.
