quran:20:119 –

And indeed, you will not be thirsty therein or be hot from the sun."  

And it is indeed ˹assured˺ for you (read wa-annaka or wa-innaka, as a supplement to the subject of inna ˹sc. laka, that is, ‘you’˺ and its clause) neither to be thirsty therein, nor to suffer the sun’: you will not be exposed to any heat of a midday sun, for there is no sun in Paradise.
القرآن:٢٠:١١٩ –

وَأَنَّكَ لَا تَظْمَأُ فِيهَا وَلَا تَضْحَىٰ  

{وأنك} بفتح الهمزة وكسرها عطف على اسم إن وجملتها {لا تظمأ فيها} تعطش {ولا تضحى} لا يحصل لك حر شمس الضحى لانتفاء الشمس في الجنة.
