Don’t Trust the hypocrites

AT-TAWBA (REPENTANCE, DISPENSATION) : 75-78

9:75. Amongst them are men who made a covenant with Allah, that if He bestowed on them of His bounty, they would give (largely) in charity, and be truly amongst those who are righteous.
9:76. But when He did bestow of His bounty, they became covetous, and turned back (from their covenant), averse (from its fulfilment).
9:77. So He hath put as a consequence hypocrisy into their hearts, (to last) till the Day, whereon they shall meet Him: because they broke their covenant with Allah, and because they lied (again and again).

9:78. Know they not that Allah doth know their secret (thoughts) and their secret counsels, and that Allah knoweth well all things unseen?
