I don’t trust colonist sources, racists who wiped out half of humanity, who’s point is to spread bad news and evil things about their enemies.
The Sayid & Ismail mirre etc were using Gabays to spread the bad things the British as well but I’d sooner trust them then the other way around.
Darswish had good and bad. Most of which was dblock civil wars and warlike mentality.
You could apply the same argument on Darawish arguing that they're spreading bad news about their enemies be it colonial powers or other Somalis. That said contemporary primary sources written shortly after the events unfolded will hold more weight than poems.
