Surah Al-Insân 76:5

إِنَّ الْأَبْرَارَ يَشْرَبُونَ مِن كَأْسٍ كَانَ مِزَاجُهَا كَافُورًا

76:5 Abrârاَبْرَارَ is derived from barraبْرَ meaning, “to be just, be truthful, to bestow bountiful gifts, to keep oath, to behave courteously”. From these meanings derive the characteristics of al-Abrârالْأَبْرَارَ as described in verses 7-10 (cf. 2:177). One has to suppress his lust, filthiness and greed in order to reach the rank of Abrâr. Here we are told that the Abrâr will take drinks tempered with camphor (Kâfûrكَافُورًا). Camphor is something that cools down, covers and suppresses. Kâfûrكَافُور symbolizes the conditions of the Abrâr in this life and in the Hereafter. Concerning this world, it represents the cooling down of animal-like passions, so that they will not lose control over their passions and animal-like desires. The use of the word Kâfûrكَافُورًا also denotes that the poison of their evil deeds is washed away when they drink the antidote - the “cup of camphor”. They also let others drink from the cups to quench their thirst for spiritual knowledge (see the following verses 6-10). Allâh confers on them in the Hereafter all sorts of reward that flow from His love and Divine realization (see verses 11-22)
