Sayyiduna Umar bin Khattab (may Allah be pleased with him) used to say: Recite the Qur'an correctly according to the rules of Arabic, for it is in Arabic; acquire understanding in the Sunnah; interpret dreams in a good manner; and when any of you relates a dream to his brother, let him say: "O Allah! If it is good, let it be for us, and if it is evil, let it be upon our enemy."
