Should the imam and the congregation raise their hands when he says the du’aa’ during the Friday khutbah?
Question

                When the imam says du’aa’ during the khutbah on Friday, should he raise his hands or not? Should the congregation raise their hands or not?.
Praise be to Allah.
    When the khateeb says du’aa’ on Friday when he is on the 
    minbar, the Sunnah is for him not to raise his hands when saying du’aa’, and 
    the members of the congregation should not raise their hands either, rather 
    it is sufficient for the imam to point with his forefinger, as is proven 
    from the Prophet  (peace and blessings of Allaah be upon him). Some of 
    the Sahaabah criticized those who raised their hands when du’aa’ was said in 
    the khutbah, because that was not the practice of the Prophet  (peace 
    and blessings of Allaah be upon him). 

    Muslim (874) narrated from ‘Umaarah ibn Ru’aybah (may Allaah 
    be pleased with him) that he saw Bishr ibn Marwaan on the minbar, raising 
    his hands, and he said: How ugly are these two hands. I saw the Messenger of 
    Allaah  (peace and blessings of Allaah be upon him) doing no more than 
    this with his hand, and he pointed with his index finger. 

    Al-Nawawi (may Allaah have mercy on him) said in Sharh 
    Muslim: This shows that the Sunnah is not to raise the hands during the 
    khutbah, and this is the view of Maalik, our companions and others. Al-Qaadi 
    narrated that some of the salaf and some of the Maalikis allowed it because 
    the Prophet  (peace and blessings of Allaah be upon him) raised his 
    hands in the Friday khutbah when he prayed for rain. But the earlier 
    scholars responded by saying that this raising of the hands was for a 
    reason. End quote. 

    If the imam prays for rain during the Friday khutbah, then it 
    is Sunnah for him to raise his hands, following the example of the Prophet 
     (peace and blessings of Allaah be upon him), and the members of the 
    congregation should also raise their hands and say Ameen to his du’aa’, 
    because of the report narrated by al-Bukhaari (933) and Muslim (897)  from 
    Anas ibn Maalik (may Allaah be pleased with him) who said: The people were 
    stricken with a drought and famine at the time of the Prophet  (peace 
    and blessings of Allaah be upon him) and whilst the Prophet  (peace and 
    blessings of Allaah be upon him) was delivering the khutbah one Friday, a 
    Bedouin stood up and said: O Messenger of Allaah, our wealth has been 
    destroyed and our children are starving; pray to Allaah for us. He raised 
    his hands and we could not see any cloud in the sky, but by the One in Whose 
    hand is my soul, no sooner had he lowered them but there appeared clouds 
    like mountains. Then he did not step down from the minbar but I saw rain 
    flowing down his beard  (peace and blessings of Allaah be upon him). 

    Shaykh Ibn Baaz (may Allaah have mercy on him) was asked: 
    What is the ruling on one who raises his hand when the khateeb is praying 
    for the Muslims in the second khutbah? Please quote the evidence, may Allaah 
    reward you. 

    He replied: Raising the hands is not prescribed in the Friday 
    khutbah or in the Eid khutbah, for the imam or the congregation. Rather what 
    is prescribed is to listen attentively to the khutbah and say Ameen to the 
    du’aa’ quietly without raising one's voice. As for raising the hands, that 
    is not prescribed, because the Prophet  (peace and blessings of Allaah 
    be upon him) did not raise his hands during the Friday khutbah or the Eid 
    khutbah, and when one of the Sahaabah saw one of the governors raising his 
    hands in the Friday khutbah, he criticized him for that and said: The 
    Prophet  (peace and blessings of Allaah be upon him) did not raise (his 
    hands). Yes, if he prays for rain during the Friday khutbah, then he may 
    raise his hands when praying for rain, because the Prophet  (peace and 
    blessings of Allaah be upon him) used to raise his hands in that situation. 
    So if he prays for rain in the Friday khutbah or in the Eid khutbah, then it 
    is prescribed for him to raise his hands, following the example of the 
    Prophet  (peace and blessings of Allaah be upon him). End quote from 
    Majmoo’ al-Shaykh Ibn Baaz (12/339). 

    And Allaah knows best.
