Final answer:
In Surah al-Buruj, the reward mentioned for believers who do good deeds is gardens beneath which rivers flow, symbolizing Paradise.
Step-by-step explanation:
The reward specifically mentioned in Surah al-Buruj for those who believe and do good deeds is gardens beneath which rivers flow, which is an allegory for Paradise (heaven). This is illustrated in the verse which says, "Indeed, those who have believed and done righteous deeds will have gardens beneath which rivers flow. That is the great success." (Quran 85:11). In Islamic tradition, entering Paradise is considered the ultimate reward for believers, where they are spared from fear and grief and enjoy eternal bliss.
