What is the measure for a Muslim man or woman to be among those who remember Allah frequently? And are the morning and evening remembrances sufficient for that?

Allah commanded His servants to remember Him often and promised them forgiveness and a great reward. Dhikr (remembrance of Allah) is among the best, purest, and highest-ranking deeds. Whoever wishes to be among those who remember Allah often should emulate the Prophet, peace be upon him, who used to remember Allah at all times. Let his tongue be moist with the remembrance of Allah, and his heart filled with His glorification and veneration. Let Allah be obeyed and not disobeyed, remembered and not forgotten, thanked and not disbelieved. Those who awaken at night with their spouses and pray two rak'ahs are inscribed among the rememberers. So, it is not sufficient to merely engage in limited remembrance; rather, the tongue must be moist and the heart full of Allah's presence and obedience.
