In The Name of Allaah, The Most Merciful, The Bestower of Mercy.

Shaikh Rabee [may Allaah preserve him] continued regarding the hypocrites- the liars…

Allaah made known the state of affairs of these people, exposed them, made it known that they are liars and described their actions to be evil. And due to their state of loss, they took these oaths and swearing by Allaah as a screen.. ..Allaah said:

إذا جاءك المنافقون قالوا نشهد إنك لرسول الله والله يعلم إنك لرسوله والله يشهد إن المنافقين لكاذبون ـ اتخذوا أيمانهم جُنة فصدوا عن سبيل الله إنهم ساء ما كانوا يعملون ـ ذلك بأنهم ءامنوا ثم كفروا فطُبع على قلوبهم فهم لا يفقهون ـ وإذا رأيتهم تعجبك أجسامهم وإن يقولوا تسمع لقولهم كأنهم خشب مسنّدة يحسبون كل صيحة عليهم هم العدو فاحذرهم قاتلهم الله أنى يؤفكون ـ وإذا قيل لهم تعالوا يستغفر لكم رسول الله لووا رءوسهم ورأيتهم يصدون وهم مستكبرون ـ سواء عليهم أستغفرت لهم أم لم تستغفر لهم لن يغفر الله لهم إن الله لا يهدي القوم الفاسقين

When the hypocrites come to you (O Muhammad), they say: “We bear witness that you are indeed the Messenger of Allah.” Allah knows that you are indeed His Messenger and Allah bears witness that the hypocrites are liars indeed. They have made their oaths a screen (for their hypocrisy). Thus they hinder (men) from the Path of Allah. Verily, evil is what they used to do. That is because they believed, then disbelieved, therefore their hearts are sealed, so they understand not. And when you look at them, their bodies please you; and when they speak, you listen to their words. They are as blocks of wood propped up. They think that every cry is against them. They are the enemies, so beware of them. May Allah curse them! How are they denying (or deviating from) the Right Path. And when it is said to them: “Come, so that the Messenger of Allah may ask forgiveness from Allah for you”, they turn aside their heads, and you would see them turning away their faces in pride. It is equal to them whether you (Muhammad) ask forgiveness or ask not forgiveness for them. Verily, Allah guides not the people who are the Fasiqin (rebellious, disobedient to Allah). [Surah Al-Munaafiqoon. Aayaat 1-6]

Allaah testified that they are liars; even if they testified to the Messengership of Muhammad and that Allaah alone has the right to be worshipped, they are still liars and do not believe in that. Allaah exposed them, because He knows their reality- the disbelief and hypocrisy they hide in their hearts. Allaah made it known that they disbelieved and believed thereafter, then they disbelieved finally; and Allaah made it known that they do not understand and that even if Allaah’s Messenger – the most virtuous amongst the creation – sought forgiveness for them, they will not be forgiven and Allaah will not guide them to Eemaan and the truth due to their [wilful] wickedness and evil. And there maybe hypocrites in the Ummah who have these characteristics and thus receive this recompense from Allaah. Unfortunately, some people think that hypocrisy has ended, whilst in reality it is something that will continue. Hudhaifah [radiyallaahu-anhu] said, “The hypocrites at present are more evil than the hypocrites during the era of Allaah’s Messenger [sallal laahu alayhi wasallam]”, so he was asked about this, then he said, “Indeed, the hypocrites used to hide their hypocrisy and these people at present make it manifest”. Whenever time elapses, they become many amongst the groups of ahlul bidah, and burden Islaam and the Muslims with their evil, plots and hypocrisy; and all of that is done under the guise of Islaam and in the name of Islaam. Many of ahlul bidah or many innovations – in the past and thereafter – related to belief and affairs of shirk are from their plots and cunning ways. So, let the Muslims be careful of these hypocrites and infiltrators within the innovated groups.
