Abu Hurairah narrated that: the Messenger of Allah said: "In the end of time there shall come men who will swindle the world with religion, deceiving the people in soft skins of sheep, their tongues are sweeter than sugar and - their hearts are the hearts of wolves.
Allah [Mighty and Sublime, is He] says: 'Is it me you try to delude or is it against me whom you conspire? By Me, I swear to send upon these people, among them, a Fitnah that leaves them utterly devoid of reason." (Tirmidhi)
Personal Comment: Although this is a Weak Hadith, the moral of the narration is still used and cited to this day as an example of lessons to be learned and a warning to deceivers of religion for worldly or immoral purposes.
Ibn Katheer quotes the same Hadith via a stronger more authenticated narration and source in his 'Tafsir' below-
"Ibn Jarir related that Al-Qurazi said that Nawf Al-Bikali, who used to read (previous Divine)
Books said, "I find the description of some members of this Ummah in the previously revealed
Books of Allah: they (hypocrites) are people who use the religion to gain material benefit .
Their tongues are sweeter than honey, but their hearts are more bitter than Sabir (a bitter plant, aloe). They show the people the appearance of sheep while their hearts hide the viciousness of wolves.
Allah said,`They dare challenge Me, but they are deceived by Me. I swear by Myself that I will send a Fitnah (trial, calamity) on them that will make the wise man bewildered. '
