Ruling on one who says We seek the help of Allaah when the verse “and You (Alone) we ask for help” is recited
Question

                During the prayer, when the person praying behind the imam hears the words “You (Alone) we worship, and You (Alone) we ask for help (for each and everything)” [al-Faatihah 1:5], can he say We seek the help of Allaah?.
Praise be to Allah.
    What the person praying behind the imam must do is to be 
    quiet and listen attentively to the recitation of his imam, because Allaah 
    says (interpretation of the meaning): “So, when the Qur’aan is recited, 
    listen to it, and be silent that you may receive mercy” [al-A’raaf 7:204]. 

    It is not permissible for him to be distracted from listening 
    attentively to his imam’s recitation, except by reciting al-Faatihah 
    himself, because the Prophet  (peace and blessings of Allaah be upon 
    him) said: “There is no prayer for the one who does not recite the Opening 
    of the Book (al-Faatihah).” Narrated by al-Bukhaari (714) and Muslim (595). 

    As for the members of the congregation saying “We seek the 
    help of Allaah” or repeating the phrase “Iyyaaka na’budu wa iyyaaka 
    nasta’een (You (Alone) we worship, and You (Alone) we ask for help (for each 
    and everything))” [al-Faatihah 1:5], the scholars both in the past and 
    in modern times have pointed out that these are innovations which must be 
    stopped. 

    Al-Nawawi (may Allaah have mercy on him) said in 
    al-Majmoo’ (4/14): 

    Many of the common people have the habit, when they hear the 
    imam say “Iyyaaka na’budu wa iyyaaka nasta’een (You (Alone) we worship, 
    and You (Alone) we ask for help (for each and everything))”, of saying
    “Iyyaaka na’budu wa iyyaaka nasta’een (You (Alone) we worship, and You 
    (Alone) we ask for help (for each and everything))”. But this is an 
    innovation which is not allowed. End quote. 

    Shaykh ‘Abd al-‘Azeez ibn Baaz (may Allaah have mercy on him) 
    said, when he was asked about that: 

    He should listen to him only, and not say “We seek the help 
    of Allaah” or anything else; rather he should listen attentively, because 
    Allaah says (interpretation of the meaning): “So, when the Qur’aan is 
    recited, listen to it, and be silent that you may receive mercy” [al-A’raaf 
    7:204]. 

    Majmoo’ Fataawa al-Shaykh Ibn Baaz 
    (29/274). 
Shaykh Ibn ‘Uthaymeen (may Allaah have mercy 
    on him) said: There is no basis for the person praying behind the imam to 
    say “We seek the help of Allaah” when the imam says “Iyyaaka na’budu wa 
    iyyaaka nasta’een (You (Alone) we worship, and You (Alone) we ask for help 
    (for each and everything))”, and this is not allowed, because when the 
    imam finishes reciting al-Faatihah, the person praying behind him should say 
    Ameen and this is sufficient, and there is no need for him to say “we seek 
    the help of Allaah.” End quote.
