Is it prescribed to boycott innovators in this day and age?
Question

                When is it prescribed to boycott innovators (followers of bid’ah)? When is it prescribed to hate for the sake of Allaah? Is it prescribed to boycott them in this day and age?
Praise be to Allah.
    The believer should analyze the situation in the light of 
    faith and sharee’ah, and ignore his whims and desires. If his shunning and 
    keeping away from the innovator will not result in a greater evil, then it 
    is prescribed, and at the very least it is Sunnah. Similarly, shunning those 
    who openly commit sin is at the very least Sunnah. But if not shunning them 
    will be more effective because one thinks that calling these innovators, 
    guiding them to the Sunnah and teaching them what Allaah has enjoined upon 
    them will be more effective in guiding them, then he should not hasten to 
    shun them, but he should hate them for the sake of Allaah just as he hates 
    the kaafirs and sinners. But his hatred for the kuffaar should be greater, 
    whilst also calling them to Allaah and striving to guide them, acting in 
    accordance with all the shar’i evidence. So he should hate the innovator in 
    accordance with the degree of his innovation, so long as it does not imply 
    kufr, and he should hate the sinner in accordance with the degree of his 
    sin, but he should also love him for the sake of Allaah in accordance with 
    the degree of his Islam and faith. From this we know that shunning depends 
    on the situation. 

    Conclusion: the most correct approach is to look at the 
    shar’i interests involved, because the Prophet  (peace and blessings of 
    Allaah be upon him) shunned some people and not others, depending on the 
    objectives of Islam. He shunned Ka’b ibn Maalik and his two companions (may 
    Allaah be pleased with them) when they stayed behind from the campaign of 
    Tabook with no excuse. He shunned them for fifty days, until they repented 
    and Allaah accepted their repentance. But he did not shun ‘Abd-Allaah ibn 
    Ubayy ibn Salool and a group of those who were accused of hypocrisy, for 
    shar’i reasons. 

    The believer looks at what is in the best interests (of 
    Islam). This does not contradict the idea of hating the kaafirs, innovators 
    and sinners for the sake of Allaah and loving the Muslims for the sake of 
    Allaah. Attention must be paid to what is in the general interest; if 
    shunning is better then they should be shunned, but if the objectives of 
    Islam dictate that ongoing da’wah efforts should be made rather than 
    shunning, then that is what should be done, following the teaching of the 
    Prophet  (peace and blessings of Allaah be upon him). And Allaah is the 
    Source of strength.
