    We ask Allaah to make you steadfast in your efforts to fulfil 
    the duty of calling people to Allaah and in your keenness to spread good. 
    Your love of good and your efforts to spread it indicate that you are a good 
    person, in sha Allah. We ask Allaah that you will be included in His words 
    (interpretation of the meaning): 

    “You (true believers in Islamic Monotheism, and real 
    followers of Prophet Muhammad and his Sunnah) are the best of peoples ever 
    raised up for mankind; you enjoin Al-Ma‘roof (i.e. Islamic Monotheism and 
    all that Islam has ordained) and forbid Al‑Munkar (polytheism, disbelief and 
    all that Islam has forbidden), and you believe in Allaah”

    [Aal ‘Imraan 3:110]
Your saying that you love 
    Allaah is the characteristic of those whom Allaah loves, of whom He says 
    (interpretation of the meaning): 

    “a people whom He will love and they will love Him”

    [al-Maa'idah 5:54]

    Whoever loves Allaah sincerely, Allaah will love him. The 
    Messenger of Allaah  (peace and blessings of Allaah be upon him) said: 
    “Whoever loves to meet Allaah, Allaah loves to meet him.” (Narrated by 
    al-Bukhaari, 6507; Muslim, 2683). 

    Al-Bukhaari (7375) and Muslim (813) narrated from ‘Aa’ishah 
    (may Allaah be pleased with her) that the Prophet  (peace and blessings 
    of Allaah be upon him) sent a man on a campaign; when he led his companions 
    in prayer, he used to end his recitation with Qul Huwa Allaah Ahad. 
    When they came back, they mentioned that to the Prophet  (peace and 
    blessings of Allaah be upon him). He told them, ‘Ask him why he does that.” 
    He said, “Because it speaks of the Most Merciful and I love to recite it.” 
    The Prophet  (peace and blessings of Allaah be upon him) said, “Tell him 
    that Allaah loves him.” This man loved the attributes of Allaah, so Allaah 
    loved him. 

    If you want to know how sincere your love for Allaah is, then 
    examine yourself in the light of the following verse, in which Allaah says 
    (interpretation of the meaning): 

    “Say (O Muhammad to mankind): If you (really) love Allaah, 
    then follow me (i.e. accept Islamic Monotheism,
    follow the Qur’aan and the Sunnah), 
    Allaah will love you and forgive you your sins”

    [Aal ‘Imraan 3:31]

    i.e., follow the Prophet  (peace and blessings of Allaah 
    be upon him). 

    If Allaah loves you, you may receive the glad tidings of 
    great goodness. Allaah says in a hadeeth qudsi: “Whoever shows enmity to 
    someone devoted to Me, I shall be at war with him. My slave draws noy near 
    to Me with anything more beloved to Me than the religious duties I have 
    enjoined on him, and My slave continues to draw near to Me with 
    supererogatory works so that I shall love him. When I love him I am his 
    hearing with which he hears, his seeing with which he sees, his hand with 
    which he strikes and his foot with which he walks. Were he to ask something 
    of Me, I would surely give it to him, and were he to ask Me for refuge, I 
    would surely grant him it. I do not hesitate about anything so much as I 
    hesitate about [seizing] the soul of My faithful slave: he hates death and I 
    hate hurting him.”

    (Narrated by al-Bukhaari, 6502). 

    The following are six benefits that a person gains by loving 
    Allaah, in order of importance: 

    1-Allah becomes his hearing, 
    i.e., he does not listen to anything except that which pleases Allaah.

    2-Allaah becomes his seeing, 
    i.e., he does not look at anything but that which pleases Allaah.

    3-Allaah becomes his foot with 
    which he walks, i.e., he does not walk for anything except that which is 
    pleasing to Allaah,

    4-Allaah becomes his hand with 
    which he strikes, i.e., he does not take revenge for himself but rather for 
    the sake of Allaah, so he does not do anything with his hand except that 
    which pleases Allaah.

    5-Allaah answers his du’aa’s

    6-Allaah grants him refuge from 
    everything that he dislikes.

    So congratulation to those whom Allaah loves, to the close 
    friends of Allaah, to the party of Allaah.  

    “They are the party of Allaah. Verily, it is the party of 
    Allaah that will be the successful” 

    [al-Mujaadilah 58:22]
With regard to 
    istikhaarah, it is prescribed when a person is thinking about doing 
    something, then he hesitates about it. But with regard the thing that you 
    are doing, namely calling people to Allaah, there is no need to pray 
    istikhaarah, rather you should go ahead and call people to Allaah with 
    wisdom and beautiful preaching. 

    With regard to the bad dream that you saw, it is from the 
    Shaytaan. The Prophet  (peace and blessings of Allaah be upon him) 
    taught us, if we see something good in our dreams, to tell those whom we 
    love about it, but if we see something bad, we should seek refuge with 
    Allaah from the Shaytaan and spit drily to the left three times, then turn 
    over onto the other side, and we should not pay attention to that bad dream.
