What are the greatest and most rewarding and beneficial morning and evening remembrances (adhkar) for protecting oneself, and when is the time for reciting them?

The greatest forms of remembrance (dhikr) are those mentioned in the Quran and Sunnah, and they can be found in books of dhikr such as "Amal Al-Yawm Wal-Laylah" (Deeds of Day and Night), "Al-Adhkar" (The Remembrances), and "Al-Wabil Al-Sayyib" (The Abundant Rain). The time for reciting morning remembrances is from after midnight until close to zawal (midday), and for evening remembrances, it is from zawal until midnight. It has also been said that morning remembrances are recited from Fajr prayer until sunrise, and evening remembrances from after Asr prayer until sunset.
