Question

                What are the ways in which a person can avoid forgetting the adhkaar for morning and evening; what are your suggestions?  

We are also very keen to learn the names of some resources on adhkaar.
Praise be to Allah.Firstly: 
Remembrance 
    of Allaah (dhikr) is one of the greatest acts of worship and best acts of 
    obedience. It is a means of rising in status. Allaah has not set any limit 
    for remembrance of Him, rather He has enjoined remembering Him a great deal. 
    Allaah says (interpretation of the meaning): 
“and 
    remember Allaah much, that you may be successful”

    [al-Jumu’ah 62:10] 
“Verily, 
    the Muslims (those who submit to Allaah in Islam) men and women, the 
    believers men and women (who believe in Islamic Monotheism), the men and the 
    women who are obedient (to Allaah), the men and women who are truthful (in 
    their speech and deeds), the men and the women who are patient (in 
    performing all the duties which Allaah has ordered and in abstaining from 
    all that Allaah has forbidden), the men and the women who are humble (before 
    their Lord ___Allaah), the men and the women who give Sadaqaat (i.e. Zakaah 
    and alms), the men and the women who observe Sawm (fast) (the obligatory 
    fasting during the month of Ramadân, and the optional Nawafil fasting), the 
    men and the women who guard their chastity (from illegal sexual acts) and 
    the men and the women who remember Allaah much with their hearts and 
    tongues. Allaah has prepared for them forgiveness and a great reward (i.e. 
    Paradise)”

    [al-Ahzaab 33:35]
In the 
    Qur’aan, Allaah does not enjoin doing any act of worship a great deal, 
    except remembrance of Allaah (dhikr). In the remembrance of Allaah hearts 
    find rest.  
“Those 
    who believed (in the Oneness of Allaah — Islamic Monotheism), and whose 
    hearts find rest in the remembrance of Allaah verily, in the remembrance of 
    Allaah do hearts find rest”
[al-Ra’d 
    13:28]
In order to 
    find out the means that help one to remember the adhkaar for the morning and 
    evening, it is essential, first of all, to find out the causes of forgetting 
    and neglecting them, then deal with these causes. 

    1.Carelessness in memorizing 
    these adhkaar and relying on booklets to recite them.

    2.Being distracted by worldly 
    matters at the expense of time for the morning and evening adhkaar.

    3.Not knowing the worldly 
    benefits of these adhkaar, such as protection for the one who recites them, 
    opening the door to provision and warding off evil for the one who recites 
    them, and the benefits in the Hereafter, such as a reward equivalent to that 
    of freeing a slave, making the Balance weigh heavily, and earning the good 
    pleasure of Allaah, may He be exalted

    4.Committing many sins, which 
    affects the person’s heart and prevents him from remembering Allaah.

    5.Ignorance of the time for the 
    morning and evening adhkaar, so he thinks that the time for the morning 
    adhkaar ends with Fajr prayer, for example, and the time for the evening 
    adhkaar ends with ‘Asr prayer, for example. In fact the time for the morning 
    adhkaar lasts until after sunrise, and the time for the evening adhkaar 
    lasts until after sunset. For more information please see question no.
    22765.
The way to 
    deal with these causes is as follows: 

    1.Try to memorize most of these 
    adhkaar so that you will be able to recite them in the car or on the way to 
    work or school, without needing the book.

    2.Pondering the meanings of these 
    adhkaar that are prescribed in Islam, because many people recite these 
    adhkaar without understanding the meanings, which weakens or cancels out 
    their effect on reforming the heart.

    3.Setting aside a specific time 
    in the morning and evening for reciting these adhkaar and sticking to it, 
    and ignoring everything that may distract you from that.

    4.Do not delay reciting these 
    adhkaar when you remember to do so, because putting off such things may lead 
    to forgetting them.

    5.Finding out what has been 
    narrated in the Qur’aan and Sunnah of the great rewards in this world and in 
    the Hereafter for the one who remembers Allaah. Undoubtedly this will 
    encourage you to remember them and not neglect them. 

    6.Keep away from sins so that 
    your heart will remain sound and sincere, longing to remember Allaah.

    7.Strive to take a gradual 
    approach in learning these adhkaar. Do not set yourself a program of 
    reciting everything that is narrated in the book of adhkaar, so that you 
    will not make things too difficult for yourself, which may lead you to give 
    up. Rather you should recite a small portion so that you can taste the 
    sweetness of dhikr, and increase it gradually.

    8.Read the biographies of 
    worshippers who strove hard in the remembrance of Allaah, so that it will 
    encourage you to follow their example and strive as they strove.

    9.Urge your wife, children and 
    family to remind one another of these adhkaar, for the believer gains great 
    support through his brothers.

    10.Seek righteous friends who will 
    help you to remember Allaah and remind you of adhkaar and acts of worship.
