Khateeb reciting in Jumu’ah prayer verses that are appropriate to the topic of the khutbah
Question

                Some khateebs doe not recite Soorat al-A’la (87) and al-Ghaashiyah (88) in Jumu’ah prayer, rather they choose passages from the Qur’aan that are appropriate to the subject of the khutbah. What is the ruling on that?.
Praise be to Allah.
    The Muslims in general should respect the Sunnah of the 
    Prophet  (peace and blessings of Allaah be upon him) and strive to learn 
    it and act upon it, because this is a sign of their sincere love for Allaah 
    and a means of them attaining Allaah’s love for them. Allaah, may He be 
    exalted, says (interpretation of the meaning): 

    “Say (O Muhammad صلى الله 
    عليه وسلم 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. And Allaah is Oft-Forgiving, Most 
    Merciful’”

    [Aal ‘Imraan 3:31]

    If the Muslim is sincere in his love of Allaah, that will be 
    manifested in his following the Prophet  (peace and blessings of Allaah 
    be upon him) in all things. The khateeb is the first one who should be 
    adhering to the Sunnah of the Prophet  (peace and blessings of Allaah be 
    upon him), because the people take him as an example, so he has to present 
    the Sunnah of the Prophet  (peace and blessings of Allaah be upon him) 
    to the people and teach them about it. 

    How can this khateeb enjoin the people to follow and venerate 
    the Sunnah of the Prophet  (peace and blessings of Allaah be upon him), 
    then come down from the minbar and openly go against the Sunnah of the 
    Prophet  (peace and blessings of Allaah be upon him)?! 

    The way of the Prophet  (peace and blessings of Allaah be 
    upon him) was to recite two soorahs in Jumu’ah prayer: 
    Sabbih isma rabbika al-A’la 
    (Soorat al-A’laa 87) and al-Ghaashiyah (88), or he would recite al-Jumu’ah 
    (62) and al-Munaafiqoon (63).  

    The Prophet  (peace and 
    blessings of Allaah be upon him) did not choose verses from the Qur’aan that 
    were appropriate to the topic of his khutbah. The best of guidance is the 
    guidance of Muhammad  (peace and blessings of Allaah be upon him). 

    Does this khateeb – or anyone else 
    – think that he is more guided than the Prophet  (peace and blessings of 
    Allaah be upon him) or that he knows something that the Prophet  (peace 
    and blessings of Allaah be upon him) did not?! 

    This action on the part of the 
    khateeb is an innovation (bid’ah) because the Prophet  (peace and 
    blessings of Allaah be upon him) did not do it. 

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

    But there is something that some 
    imams do: when they give a khutbah then recite in the prayer verses that are 
    appropriate to it. This may be described as an innovation, because the 
    Messenger  (peace and blessings of Allaah be upon him) always recited
    Soorat al-A’la (87) and al-Ghaashiyah (88), or
    al-Jumu’ah (62) and 
    al-Munaafiqoon (63), and he did not pay any attention to the topic of the 
    khutbah. End quote. 

    Liqaa’aat al-Baab il-Maftooh 
    (155/18). 

    Shaykh Bakr Abu Zayd said: 

    The Prophet  (peace and 
    blessings of Allaah be upon him) always did three things in his recitation 
    in Jumu’ah prayer: he recited al-Jumu’ah (62) and al-Munaafiqoon (63), or 
    al-Jumu’ah and al-Ghaashiyah (88), or al-A’la (87) and al-Ghaashiyah. 

    Nowadays it has become common for 
    some of them to ignore that which is prescribed and recite whatever verses 
    the imam sees fit, or soorahs of the Qur’aan that are appropriate to the 
    subject of the khutbah. 

    This striving to recite something 
    that was appropriate to the topic of the khutbah was not narrated from the 
    Prophet  (peace and blessings of Allaah be upon him) and was not known 
    among the early generations of this ummah, so adhering to that is an 
    innovation. Similarly, deliberately ignoring what is prescribed and doing 
    something else implies that one believes that there is something missing in 
    what is prescribed and it should be made up, and that may cause confusion to 
    ordinary Muslims. And Allaah knows best. End quote.
