Ruling on giving charity to one who follows some innovations (bid’ahs)
Question

                Is it permissible to give charity and financial help to one who follows some innovations?.
Praise be to Allah.Undoubtedly helping a 
    Muslim, relieving his distress, meeting his needs and guarding him against 
    loss are all part of the befriending of one another that is a basic 
    requirement of faith, as Allaah says (interpretation of the meaning): 
“The believers, men and 
    women, are Awliyaa’ (helpers, supporters, friends, protectors) of one 
    another; they enjoin (on the people) Al‑Ma‘roof (i.e. Islamic Monotheism and 
    all that Islam orders one to do), and forbid (people) from Al‑Munkar (i.e. 
    polytheism and disbelief of all kinds, and all that Islam has forbidden); 
    they perform As-Salaah (Iqaamat-as-Salaah), and give the Zakaah, and obey 
    Allaah and His Messenger. Allaah will have His Mercy on them. Surely, Allaah 
    is All-Mighty, All-Wise”

    [al-Tawbah 9:71]

    This is also indicated by the words of the Prophet  
    (peace and blessings of Allaah be upon him): “The believer is the mirror of 
    his fellow believer, and the believer is the brother of his fellow believer. 
    He guards him against loss and protects him when he is absent.” Narrated by 
    Abu Dawood, 4918; classed as hasan by al-Albaani. 

    With regard to the words “he protects him against loss”, Ibn 
    al-Atheer said:  A man’s loss may be with regard to handicrafts, commerce, 
    agriculture etc., so his fellow believer supports him and tries to help him 
    to earn a living.  

    The words “and protects him when he is absent” mean he 
    protects him and defends him as much as he can. See ‘Awn al-Ma’bood. 
And the Prophet  
    (peace and blessings of Allaah be upon him) said: “The relationship between 
    one believer and another is like a structure, parts of which support other 
    parts,” and he interlaced his fingers. Narrated by al-Bukhaari, 481; Muslim, 
    2585. 

    Al-Nawawi said: These words – “The relationship between one 
    believer and another is like a structure, part of which support other parts” 
    – clearly indicate the importance of the Muslims’ rights over one another, 
    and encourage them to show compassion, kindness and support to one another, 
    but not in sin or in anything bad. 

    There are many texts of the Qur’aan and saheeh Sunnah which 
    speak of such matters, all of them pointing towards befriending, supporting 
    and protecting on the basis of faith and Islam. That must be the basis for 
    loving and hating, giving and withholding, as the Prophet  (peace and 
    blessings of Allaah be upon him) said: “Whoever gives for the sake of Allaah 
    and withholds for the sake of Allaah, loves for the sake of Allaah and hates 
    for the sake of Allaah, and gets married for the sake of Allaah, has 
    perfected his faith.” Ahmad, 1519; al-Tirmidhi, 2521; Abu Dawood, 4681; 
    classed as hasan by al-Albaani. 
People vary with regard 
    to faith and Islam. Some of them fear Allaah and have faith more than 
    others. Thus each person varies in the degree to which he is entitled to the 
    rights of friendship, depending on the degree of his religious commitment, 
    although they all come under the general heading of the friendship that is 
    required in Islam. 

    Shaykh al-Islam Ibn Taymiyah (may Allaah have mercy on him) 
    said in al-Fataawa, 28/209: 

    Allaah sent the Messengers and revealed the Books so that the 
    religion (worship) would all be for Allaah, so that love would be for His 
    close friends and hate for His enemies; so that His close friends would be 
    honoured and His enemies humiliated; so that the reward would be for His 
    close friends and the punishment would be for His enemies. If good and evil, 
    obedience and disobedience, Sunnah and bid’ah, coexist in a person, then he 
    is deserving of friendship and reward to the extent that he is good, and he 
    deserves enmity and punishment to the extent that he is bad. So the reasons 
    for honouring and humiliating may coexist in a person; both may coexist in 
    him – such as a poor thief whose hand is cut off for stealing, but he is 
    given enough from the bayt al-maal (treasury) to meet his needs. 

    This is the basic principle upon which Ahl al-Sunnah 
    wa’l-Jamaa’ah are agreed… 

    The answer to this question is based on this general 
    principle. Shaykh Ibn ‘Uthaymeen (may Allaah have mercy on him) said:  

    There is some bid’ah for which a person may be excused, there 
    is some which reaches the degree of fisq (evildoing) and there is some that 
    reaches the degree of kufr. With regard to those who follow bid’ah that 
    constitutes kufr, it is not permissible to help them at all, even if they 
    call themselves Muslims, because their calling themselves Muslims whilst 
    they persist in that bid’ah that constitutes kufr, even after evidence has 
    been established against them, means that they are akin to the hypocrites 
    who said, “we bear witness that you are the Messenger of Allaah,” but Allaah 
    said (interpretation of the meaning): 
“Allaah knows that you 
    are indeed His Messenger, and Allaah bears witness that the hypocrites are 
    liars indeed”

    [al-Munaafiqoon 63:1]

    With regard to innovation that constitutes fisq (evildoing), 
    or for which a person may have a justifiable excuse, the fact that they 
    follow bid’ah does not mean that we are not allowed to help them. They 
    should be helped against their kaafir enemies because they are undoubtedly 
    better than those kuffaar. Al-Baab al-Maftooh, 1/66 
But they should be 
    prevented from spending this money on establishing or propagating their 
    bid’ahs. If it is known or it is thought most likely that they will use that 
    money to support their bid’ahs, and they cannot be stopped from doing so, 
    and they will not spend it on permissible things that they need, then they 
    should not be given any of this money, because that entails helping them in 
    their sin. Allaah says (interpretation of the meaning):

     “Help you one another in Al‑Birr and At‑Taqwa (virtue, 
    righteousness and piety); but do not help one another in sin and 
    transgression. And fear Allaah. Verily, Allaah is Severe in punishment”

    [al-Maa'idah 5:2]

    And Allaah is the Source of strength and the Guide to the Straight Path.
