Shaikh Rabee (may Allaah preserve him) said:

Some people are well known for lying and inconsistency, so he acts as if he is repentant.  So regarding this person, we say: Inshaa-Allaah your repentance is accepted, but we are cautious of him until he manifests his correct repentance. [Siyaanatus Salafi’ pages 79-80]

Note: Masjid Al-Furqan promoted sayyid qutb’s books of misguidance, but they have kept quiet for a year about his misguidance. This type of silence is nothing else but a desire to hide the truth. It has been stated that the reality of lying is to give news of something in opposition to the true state of affairs. This transmission of news is not limited to speech, rather it can be through action, such as making an indication with one’s hand or nodding one’s head and it can be through silence. It is also said that the liar is a thief, because the thief deceives you with regards to your wealth and the liar deceives you with regards to your intellect.
