Revival Sunnah

It is reported from Al-Hasan Al-Basri – may Allah have mercy on him – that he said:"It used to be said: it is part of an-Nifaaq (hypocrisy) to be inwardly different from what you are on the outside, to say one thing and do another and to be different in how you enter and how you leave. And the root of an-Nifaaq is lying."[Abu Bakr Al-Kharaa'iti, Masaawee Al-Akhlaaq wa Madhmoomihaa, p62.]
