Reciting Quran by Heart
Scholars have said that whoever sees themselves reciting the Holy Quran from memory (by heart) in a dream, it may indicate that they are trustworthy and upright in truth. It also suggests that they enjoin what is right and forbid what is wrong, in accordance with the noble Quranic verse describing these qualities.
