These are some timely narrations collected by Muhammad Musa Nasr in his book ‘al-Munafiqun’ (p. 95-98). They are all authentic.

1 – Jubayr bin Nufayr said:

“I went to visit Abu ad-Darda’ at his home in Homs, and I found him praying at his mosque. When he sat for the tashahhud, he began seeking refuge with Allah from hypocrisy. When he finished, I went to him and asked: “May Allah Forgive you, Aba ad-Darda’! What do you have to do with hypocrisy?”

He replied: “O Allah, Your Forgiveness! (he said this three times) Nobody who feels safe from tribulation will be safe from it! By Allah, a man can be tested for a single hour and turn back on his religion.”"

2 – ‘Abdullah bin ‘Amr said:

“There will come a time when people will gather in their mosques, and there won’t be a single believer in them.”

3 – Al-Hasan said:

“The Hour will not come until each people will be overwhelmed by their hypocrites.”

4 – Hudhayfah said:

“The hypocrites among you today are worse than the hypocrites who lived at the time of the Messenger of Allah (صلى الله عليه و سلم)!”

He was asked: “O Aba ‘Abdillah, how is this so?”

He replied: “They used to hide their hypocrisy. As for the ones today, they display it openly.”
