The word(s) "bitter" appears 6 time(s) in 6 verse(s) in Quran in Mohsin Khan translation.

(1) "And We shall remove from their breasts any deep feeling of bitterness (that they may have). (So they will be like) brothers facing each other on thrones.

(2) And it is He Who has let free the two seas (kinds of water): this is palatable and sweet, and that is salt and bitter; and He has set a barrier and a complete partition between them.

(3) But they turned away (from the obedience of Allah), so We sent against them Sail Al-'Arim (flood released from the dam), and We converted their two gardens into gardens producing bitter bad fruit, and tamarisks, and some few lote-trees.

(4) And the two seas (kinds of water) are not alike: this is palatable, sweet and pleasant to drink, and that is salt and bitter. And from them both you eat fresh tender meat (fish), and derive the ornaments that you wear. And you see the ships cleaving (the sea-water as they sail through it), that you may seek of His Bounty, and that you may give thanks.

(5) Nay, but the Hour is their appointed time (for their full recompense), and the Hour will be more grievous and more bitter.

(6) Reclining therein on raised thrones, they will see there neither the excessive heat of the sun, nor the excessive bitter cold, (as in Paradise there is no sun and no moon).
