The Harm and Danger That Surrounds a Person Who Sits With a Mubtadi
In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
Imaam Sufyaan Ath-thawri [rahimahullaah] said, ‘’The one who sits with a person of innovation is not safe from one of three [calamities]: Either he becomes a trial for other than himself; or something of [misguidance] enters into his heart, and thus he slips by way of that and Allaah enters him into the hell fire; or he says, ‘By Allaah, I don’t care what they say because I am sure of myself’. But whoever feels safe about his religion [i.e. without Allaah’s guidance, protection etc] in the twinkling of an eye, it will be snatched away from him”.
