Sufism is strong in Somalia, especially Galmudug and HG Ceyr subclans. I have family that is sufi and while Im not sufi ( more mainstream somali shafici muslim) I do see influences of sufism in the way my family practises Islam.
I can definitely tell you that in Gaalkacyo, sufism is big there.
You have a choice there: Either tableeqis or sufi majids. The sufi masjids do the dhikr singing after salaad and throw mowlids for every dead ancestor and their cat. The tableeqi masjids are similar to masjids in the West but with some minor differences.
