Adding onto the question about Zakat and Sadaqa, I think they held significant importance Muslims in hiding or enslaved because they were easier to accomplish than other pillars. Charity giving, although not as emphasized also holds significant importance in Christianity. In addition both can be understood as forms of nonviolent resistance. As you mentioned they can be understood as a sign of solidarity and this makes me think of the dance capoeira that Brazilians practiced. This was a form of non-violent resistance because they passed of something cultural such a dance, when it was actually a martial art and they were training for a revolution. Obviously Zakat holds a very different meaning, but Muslims were still helping their community grow so their actions can be seen as a force of psychological resilience instead of physical. Also, Diouf speaks about this allowed Muslims to assert their autonomy economically.
