Ḥudhayfah b. Al-Yamān – Allāh be pleased with him – said:

The munāfiqūn (hypocrites) amongst you today are worse than those in the time of Allāh’s Messenger – Allāh’s praise and peace be upon him.

He was asked, “How is that o Abū ʿAbdillāh”?
He replied:
Because those [in the time of the Prophet] used to hide their nifāq (hypocrisy), whereas the hypocrites of today commit [hypocrisy] openly.
