All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.
What you have mentioned does not make Riba (interest and/or usury) permissible. Also, there is no harm in taking money from the government in a legitimate manner. Revealing your face in case of necessity is less serious than being involved in Riba, because anyone who consumes Riba or gives it to others to consume has been cursed; so Riba is only permissible in case of necessity. Allaah says (what means): {But whoever is forced [by necessity], neither desiring [it] nor transgressing [its limit], there is no sin upon him. Indeed, Allaah is Forgiving and Merciful.} [Quran 2:173]
The degree of necessity that makes it permissible to consume what is forbidden is when a person with full legal capacity is in a situation whereby if he does not consume what is forbidden he will die or experience extreme hardship which he cannot endure without significant harm, and this hardship cannot be avoided except by consuming what is forbidden. For more benefit, please refer to Fatwa 103791.
Allaah knows best.
