Falseness of the claims about the tenth planet
Question

                What is your opinion about the so-called tenth planet or “death planet” that is expected to approach on 15/5/2003 and cause widespread destruction? There are people who say that this is true and that it is mentioned in the Holy Qur’aan, in Soorat al-Taariq. 

Please advise us, may Allaah have mercy on you, because the people who say this are calling upon the people to leave their homes and flee to other places if they want to survive.
Praise be to Allah.Shaykh 
    Haamid al-‘Ali was asked on his website about this question and he said: The 
    Muslim should be sure of three things when he hears this kind of news: 
1 – That 
    life on earth will never come to an end except as described in the Book of 
    Allaah and the Sunnah of His Prophet  (peace and blessings of Allaah be 
    upon him). The end of history will never occur before the emergence of all 
    of the lesser and greater signs of the Hour. One of those signs is that 
    there will be conflict between the people of truth, who are the Muslims, and 
    the people of evil and falsehood, who are all of those who oppose the 
    religion of truth, Islam, and strive to extinguish its light. There are two 
    distinct features of this conflict which will occur before the end of life. 
    The first is a conflict between the Muslims and the people of the cross, as 
    is mentioned in the saheeh ahaadeeth which speak of the battles at the end 
    of time. 
The second 
    is the battle between the Muslims at the time of the descent of ‘Eesa (peace 
    be upon him) with the Dajjaal and his followers among the Jews. Then Ya’jooj 
    and Ma’jooj (Gog and Magog) will appear, and they will die as one. 
Then the 
    Muslims will rule the earth, then everyone in whose heart is faith equal to 
    a grain of corn will die, when a cold wind blows that will take the souls of 
    the believers. Then the Hour will begin soon after that and it will come 
    upon the most evil of people who are scattered throughout the earth. The 
    universe will not be destroyed when there is still one believer on earth, 
    but when faith is gone it will be destroyed, because belief in Allaah is a 
    reason for life to continue. 
The point is 
    that it is not permissible for a Muslim to believe that the end of the world 
    will occur in a manner different to that which is mentioned in the proven 
    texts of the Book of Allaah and the Sunnah of His Prophet  (peace and 
    blessings of Allaah be upon him). 
2 – It is 
    not permissible for a Muslim to believe that heavenly bodies can bring 
    benefit or ward off harm, or that they can bring provision or bring joy or 
    sorrow, or that they have any control on the lives of men, and so on. This 
    is a polytheistic belief (shirk) which is held by people of Jaahiliyyah. It 
    is stated in the saheeh ahaadeeth that whoever believes in this is guilty of 
    kufr. Thus it is clear that all claims made by astrologers are lies, kufr 
    and shirk (the association of others with Allaah, may He be exalted). 
The planets 
    are no more than bodies that are subject to the decree of Allaah and play 
    their role in the universe. This does not mean that they do not behave 
    according to the natural laws according to which Allaah has established the 
    universe or have an effect on one another, as a result of which calamities, 
    disasters and earthquakes occur. Shaykh al-Islam Ibn Taymiyah mentioned that 
    eclipses affect the earth. The Prophet  (peace and blessings of Allaah 
    be upon him) said: “A sign by means of which Allaah instils fear in His 
    slaves” i.e., it points to the approach of events that have been decreed by 
    Allaah, may He be glorified and exalted, in order to instil fear and remind 
    people of Allaah, an eloquent reminder of His power, a reminder of the end 
    of the world, a reminder to him not to transgress and to remember always 
    that he is on the earth of Allaah which, if He willed, He could cause to 
    shake beneath his feet, and he would not be able to do anything. 
Hence 
    earthquakes usually happen after eclipses, as do destructive storms. We seek 
    refuge with Allaah from His wrath. He mentioned that the Prophet  (peace 
    and blessings of Allaah be upon him) sought refuge with Allaah from the 
    moon, because it has an effect, otherwise why would he seek refuge from it? 
    But its effect is physical in nature like other physical effects that Allaah 
    has created. 
So long as 
    the Muslim believes that this all happens by the will and decree of Allaah, 
    and that they are signs by means of which Allaah instils fear in His slaves, 
    then it does not matter. But it is essential to understand the relationship 
    between the movement of the planets and the sun and the movements of the 
    earth, and the layers of the earth and the movement of the winds, on a 
    scientific basis, and the interaction of natural scientific laws. Islam does 
    not forbid that, rather it enjoins us to discover the laws of the universe 
    that Allaah has created. 
3 – It is 
    not permissible for a Muslim to ignore the ahaadeeth in which the Prophet 
     (peace and blessings of Allaah be upon him) spoke of what is to happen 
    in the future in favour of what is said by scientists and astronomers whose 
    words may be based on conjectures or expectations which soon be shown to be 
    wrong. It is not valid for anyone to say that the fall of America, the 
    emergence of the Mahdi, or the change in the global system or the balance of 
    power will come as the result of the movement of the planets which will have 
    a disastrous effect on the earth, in such and such a year, etc. 
Whoever 
    states such a thing is speculating and speaking without knowledge, speaking 
    about the unseen with no knowledge. If he is speaking within the framework 
    of possibility, and what could happen, well many things could happen, but no 
    one knows what is going to happen, and when, except Allaah alone. 
We have been 
    commanded to strive against our enemies with what we have been given of 
    strength, and to strive to surpass them, or to be equal to them, or to come 
    close to them in terms of the physical and moral resources that they have, 
    and not to rely on natural calamities  to destroy our enemies. 
We know from 
    the seerah of our Prophet  (peace and blessings of Allaah be upon him) 
    that we should face our enemies with reliance upon Allaah first and 
    foremost, then by means of the deep faith in our beliefs that Allaah has 
    given us, and with firm resolve to reclaim our rights, patience in adhering 
    to our path and persistence in conveying the message and ongoing jihad, 
    until we reach our goal and our highest aim, which is to lead mankind to 
    guidance and light, so that all of mankind may enjoy the message of mercy 
    with which our Prophet  (peace and blessings of Allaah be upon him) was 
    sent. This is what he  (peace and blessings of Allaah be upon him) did 
    during his lifetime, and we have the best of examples in him. 
After this, 
    we say that what this speaker has said about the planet Nibiru is worthless 
    until it is proven by sound scientific evidence. If this planet is to have a 
    destructive effect by passing close to the earth, and that is proven, then 
    what we have to do is adhere to the three guidelines mentioned above, and 
    turn to Allaah, praying to Him to avert disaster, and if it happens to 
    relieve us of it, and to make the consequences better for us and the 
    Muslims. 
But we think 
    that everything that is said about this planet is a fabrication that has no 
    basis in truth, or it is an exaggeration, and it is unwise to pay any 
    attention to it.  
And Allaah 
    knows best. 
What the 
    questioner mentioned in his question has occurred in the past, and nothing 
    happened, which confirms the idea that this is speculation and speaking 
    without knowledge.
