Is seeing Allaah is a dream possible?
Question

                Is seeing Allaah is a dream possible or not?.
Praise be to Allah.
    Seeing Allaah in this world is definitely not possible. The 
    evidence for that is the fact that Moosa, who was one of the greatest 
    Messengers and one of the five Messengers of strong will said: “ ‘O my 
    Lord! Show me (Yourself), that I may look upon You’” Allaah said to him:
    “ ‘You cannot see Me, but look upon the mountain; if it stands still in 
    its place then you shall see Me.’ So when his Lord appeared to the 
    mountain, He made it collapse to dust.” So the mountain crumbled before 
    Moosa as he was looking on, and “Moosa (Moses) fell down unconscious” 
    So he lost consciousness, because he was watching something that he could 
    not bear. “Then when he recovered his senses he said: ‘Glory be to You, I 
    turn to You in repentance and I am the first of the believers.’” 
    [Quotations from al-A’raaf 7:143 – interpretation of the meaning]. So he 
    repented to Allaah for having asked this question, because it was asking for 
    something that was not possible, and Allaah says (interpretation of the 
    meaning): 

    “Invoke your Lord with humility and in secret. He likes 
    not the aggressors”

    [al-A’raaf 7:55]
Seeing Allaah in this 
    world when one is awake is something that is not possible. Even the Prophet 
     (peace and blessings of Allaah be upon him) on the night of the Mi’raaj 
    (ascent into heaven) did not see his Lord. He was asked ‘Did you see your 
    Lord?’ He said, “I saw Light.” According to another report: “Light – how 
    could I see Him?” i.e., between me and Him there was a great veil of light. 
    According to a hadeeth in al-Saheeh, it is narrated that Allaah is 
    veiled in Light. That appears in the hadeeth in which the Prophet  
    (peace and blessings of Allaah be upon him) said: “His veil is Light and if 
    He were to remove it, the glory of His Countenance would burn everything of 
    His creation, as far as His gaze reaches.” Because His sight reaches 
    everything, and everything would be burned by this immense Light. Based on 
    this, we say that it is not possible to see Allaah in this world when one is 
    awake. 

    As for dreams, the Prophet  (peace and blessings of 
    Allaah be upon him) saw his Lord in a dream, but is it possible for anyone 
    else to see Him? It is narrated that Imam Ahmad (may Allaah have mercy on 
    him) saw his Lord, and some of the scholars said that this is possible. And 
    Allaah knows best. But I am afraid to open the door to Sufi shaykhs and 
    others who will start saying, “I saw my Lord last night and we chatted and 
    talked together,” then he will come up with myths and lies for which there 
    is no basis. I think it is better to keep this door closed from the outset.
