The Prophet's Prohibition
Against Being A Conformer,
Rather, Let One Practice Goodness
And Follow Truth
It is narrated from Hudhayfa (ra) that he said:
Allah's Messenger said: "Do not be
conformers who say: `If people do good we shall do
good, and if they do wrong we shall do wrong.' Rather,
make yourselves ready to do good if people do good,
and, if they do wrong, not to do wrong."
Al-Tirmidhi narrated it and declared it hasan, as
stated in al-Targhib and elsewhere.
