In The Name of Allah, The Most Merciful, The Bestower of Mercy.

The Shaikh, may Allah have mercy upon him, said:

If your brother makes a mistake, advise him gently and present proof and evidence for Allah to benefit him through that. But as for sitting and waiting for so and so to make a mistake, then smearing here and there that so-and-so did such-and-such, these are the ways of the devils, not the ways of the Salafis.
