It is narrated from Hazrat Abu Darda (may Allah be pleased with him) that once the Noble Prophet (peace and blessings be upon him) said to the companions (may Allah be pleased with them): "Are you incapable of reciting one third of the Qur'an in a single night?" This seemed very difficult to the companions (may Allah be pleased with them) and they said, "Who would have the strength to do that?" The Noble Prophet (peace and blessings be upon him) said, "Recite Surah Ikhlas, for it is equal to one third of the Qur'an."
