Question

                Is the supplication, “O Allah, show us a bad day for them” regarded as reviling or inveighing against time?.
Praise be to Allah.
      Firstly: 

    This supplication is not narrated in any report and we did 
    not find it in any of the books of Sunnah. 

    Secondly: 

    There is nothing wrong with using these words in supplication 
    and it is not regarded as inveighing against time. What is meant is 
    describing the day as very difficult and stressful. This is like the words 
    of Loot (peace be upon him): “This is a distressful day” [Hood 11:77]. 
    It is also like the words of Allah, may He be glorified and exalted 
    (interpretation of the meaning):

    “Verily, We sent against them a furious wind of harsh 
    voice on a day of evil omen and continuous calamity”

    [al-Qamar 54:19]

    “So We sent upon them a furious wind in days of evil omen 
    (for them)…”

    [Fussilat 41:16]

    and there are other similar verses which describe or speak of 
    hardship and distress but are not intended to inveigh against the day or 
    criticise it. There is a difference between merely telling and intending to 
    criticise, revile and undermine. 

    Moreover, describing the day as “bad” does not mean that it 
    is bad for everyone; rather what is meant is that it is only bad for them 
    because of what they go through – by the decree or the power of Allah – of 
    punishment and vengeance. 

    Ibn al-Qayyim (may Allah have mercy on him) said: 

    No doubt the days on which Allah sent His punishment against 
    His enemies and the enemies of His Messengers were days of evil omen for 
    them, because the evil omen befell them, even though these were the days 
    that were good for His believing close friends. So they were days of bad 
    fortune for the disbelievers and days of good fortune for the believers. 
    This is like the Day of Resurrection; it will be hard for the disbelievers 
    and a day of evil omen for them, but it will be easy for the believers and a 
    day of joy for them. Mujaahid said: “Days of evil omen” mean bad fortune… 
    With regard to good and bad fortune, good fortune is connected to good deeds 
    that are pleasing to the Lord, and bad fortune is connected to deeds that go 
    against what the Messengers brought. One day may be a day of good fortune 
    for some people and a day of bad fortune for others, as the day of Badr was 
    a day of good fortune for the believers and a day of bad fortune for the 
    disbelievers. End quote. Miftaah Dar al-Sa‘aadah, 2/194 

    Shaykh Ibn ‘Uthaymeen (may Allah have mercy on him) said: 

    Inveighing  against time is of three types: 

    1.

    Where it is just a statement without expressing discontent. 
    This is permissible. For example one might say, “The heat (or cold) today is 
    unbearable” and the like. That is because actions are judged by intentions 
    and such words are merely a statement. Another example is the words of Loot 
    (peace be upon him): “This is a distressful day” [Hood 11:77]. 

    2.

    Inveighing against time as if it is the cause, such as 
    believing when inveighing against time that time is what changes things or 
    decides what is good and bad. This is major shirk because it is a belief 
    that there is another creator with Allah, because this is attributing events 
    to something other than Allah. Everyone who believes that there is another 
    creator with Allah is a disbeliever, just as the one who believes that there 
    is another god with Allah who is deserving of worship is a disbeliever. 

    3.

    Inveighing against time not because of any belief that it is 
    the cause; rather he believes that Allah is the cause, but he inveighs 
    against time because it is within the framework of time that these disliked 
    things take place. This is haraam, even though it does not go as far as 
    shirk, and it is foolish thinking and misguidance in religious terms, 
    because in fact his inveighing against time reflects on Allah, may He be 
    glorified. That is because Allah, may He be exalted, is the One Who is in 
    control of time and Who decides what happens in it of good or bad. So time 
    is not the cause and this inveighing against it does not constitute kufr, 
    because he is not inveighing against Allah, may He be exalted, directly.
