In The Name of Allaah, The Most Merciful, The Bestower of Mercy
It is with great regret that many people fall into Bidah Aqaa’idiyyah and Manhajiyyah [i.e. innovations related to beliefs and methodology], bidah related to acts of worship and other than that. Then he [i.e. the person upon such a path] is notified, but does not take notice; advised but does not accept advice. This is [tantamount to] being forsaken [by Allaah]! And from the signs that [one is following the path to happiness in this Dunyah and Aakhirah] is that he is eager to [follow] the truth, searches for it and rejoices when he is notified of his error, [saying], “May Allaah have mercy upon the person who shows me my faults” – the person who shows you your mistake, clarifies your mistake for you and that you are following the path of misguidance, that you are following other than the methodology [ordained] by Allaah and [a path other than] the Siraat Al-Mustaqeem.
