Surah 15. Al-Hijr, Ayah 47

I.e., all being equal in dignity, and therefore free from envy. As Razi points out, the plural noun surur (sing. sarir), which literally denotes "couches" or, occasionally, "thrones", signifies also "seats [or "thrones"] of eminence" or "of happiness (surur)", from which latter word the noun sarir and its plural surur may be derived. The sublime quality of these "thrones of happiness" is in some instances further symbolized by expressions like "gold-encrusted" ( 56:15 ) or "raised high" ( 88:13 ).

 i.e., the bitterness they had in their hearts towards other believers who wronged them in the worldly life.

Cf. vii. 43, and n. 1021. The hearts and minds will be so purified that all past rancour, jealousy, or sense of injury will be obliterated. The true Brotherhood will be realised there, when each will have his own dignity, there will be no question of invidious comparisons; each will face the others with joy and confidence. There will be no sense of toil or fatigue, and the joy will last for ever.
