Bangladeshi Sufism differs from other types of Sufism in SA. Sufism in BD you could easily notice the infusion of hindu culture mixed with Islam, for example the Salaam'ing of feet (I believe it is called Qadamposi in BD). Btw, let me make the distinction of the two types of Deobandi's, there's the Deobandis that lean more towards Sufism and the Deobandi Salafis, BD'eshis are more Deobandi sufis.
Most of the charity organisations in Gaza are mainly Bangladeshi run. Human aid, Muslim aid, etc, these are the main ones who have raised the money money and have the most Charity aid workers in Gaza...They have sent ambulances, food, clothes etc....
