And know that whatever thing you gain, a fifth of it is for Allah and for the Messenger and for the near of kin and the orphans and the needy and the wayfarer, if you believe in Allah and in that which We revealed to Our servant, on the day of distinction, the day on which the two parties met; and Allah has power over all things.

So He made hypocrisy to follow as a consequence into their hearts till the day when they shall meet Him because they failed to perform towards Allah what they had promised with Him and because they told lies.

And on the day when He will gather them as though they had not stayed but an hour of the day, they will know each other. They will perish indeed who called the meeting with Allah to be a lie, and they are not followers of the right direction.
