Jealousy & hatred is removed in Jannah

قال الله تعالى : { ونزعنا ما في صدورهم من غلٍّ تجري من تحتهم الأنهار وقالوا الحمد لله الذي هدانا لهذا وما كنا لنهتدي لولا أن هدانا الله لقد جاءت رسل ربنا بالحق ونودوا أن تلكم الجنة أورثتموها بما كنتم تعملون } الأعراف / 43 .

“And We shall remove from their breasts any (mutual) hatred or sense of injury (which they had, if at all, in the life of this world); rivers flowing under them, and they will say: ‘All the praises and thanks be to Allaah, Who has guided us to this, and never could we have found guidance, were it not that Allaah had guided us! Indeed, the Messengers of our Lord did come with the truth.’ And it will be cried out to them: ‘This is the Paradise which you have inherited for what you used to do’”

It is proven in as-Saheehayn (Bukhaari 3033; Muslim 2835) from Abu Hurayrah, from the Prophet (blessings and peace of Allah be upon him): “The first group to enter Paradise will look like the moon when it is full, and those who come after them will look like the most brilliant star in the sky. Their hearts will be as one, and there will be no rancour or envy among them. Each man among them will have two wives al-hoor al-‘iyn whose marrow can be seen beneath their bones and flesh.” This version was narrated by al-Bukhaari.
