Do bank profits become permissible and pure if the zakat paid on them is greater than their original value?

The benefits from usurious banks are forbidden by the consensus of scholars. Several esteemed scholarly bodies have issued rulings to this effect, including the resolution of the Academy of Islamic Research at Al-Azhar in 1965 CE, which stipulated that interest on all loans is forbidden usury. Also, the resolution of the Islamic Fiqh Academy, affiliated with the Organization of Islamic Conference, in 1985 CE, deemed any increase on debt and loans as forbidden usury. Furthermore, a resolution was issued by the Islamic Fiqh Academy, affiliated with the Muslim World League, in 1986 CE, affirming that money generated from usurious interest is forbidden and must be disposed of by spending it on general Muslim welfare. It is impermissible to leave it with banks to strengthen them. Dealing with usurious banks must be cut off whenever possible.
