Your last quote should read "traders from Somalia". They were Shirazis.

Painting from the Portuguese period of Cefala (from a book in the library of the Japanese Emperor.)
"Sofala, is a Mozambique seaport on the east coast of Africa, at the mouth of a river of the same name.
The town possesses scarcely a trace of its former importance, and what trade it had was nearly all taken away by the
establishment of Beira a little to the north in 1890. Sofala harbor is silting up and is obstructed by a bar. Ruins exist of
the strong fort built by the Portuguese in the 16th century. The Cathedral of Largo do Munica Apio is found on Av.
Eduardo Mondlane. The cathedral was erected in 1925 and is partially built of stone from the sixteenth century Fort of
Sofala which has since been flooded beneath the sea. Previous to its conquest by the Portuguese in 1505 Sofala was
the chief town of a wealthy Moslem state, Arabs having established themselves there in the 12th century or earlier. At
one time it formed part of the sultanate of Kilwa. The wealth of the town depended on trade in ivory and other goods,
but the most important commodity was gold. Gold was mined in the area of present day Zimbabwe and taken to the
coast at Sofala (present-day Beira), from which it was shipped up the coast via Kilwa. There was also an overland route
from Kilwa to Lake Nyasa and the Zambezi but this was always secondary to the sea routes. Sometime in the thirteenth
century the sultans of Kilwa seem to have gained direct control of Sofala. They lost the control shortly before the coming
of the Portuguese.
Inland the gold mining was in the hands of various kingdoms, the oldest was: The city-state of Mapungubwe, located on
the southern banks of the Limpopo River, rose during the tenth century after establishing control over the gold trade.
With the demise of Mapungubwe power shifted south to the Great Zimbabwe. Scholars speculate that the founders of
the Great Zimbabwe Kingdom owed their wealth to control of the twelfth-century trade in gold from the Save River valley.
Skeletons have been discovered at the bottom of narrow, ancient mining shafts in the region. At the peak of the trade,
an estimated 1000 kg of gold passed through Great Zimbabwe annually. The port cities of Sofala and later Kilwa
flourished from the commerce. After Great Zimbabwe collapsed around 1450, a succession of gold-trading dynasties
originated in the region of present-day Zimbabwe and Mozambique, beginning with Mutapa and Torwa in the fifteenth
century, and followed by Rozwi in the seventeenth century.
The city and harbour before the Portuguese
----------------------------------------------------
At Sofala there were two villages: one close to the sea, on a sand flat forming the north-eastern point, contained about four hundred
inhabitants; the other, a couple of miles higher up the bank of the estuary, also contained about four hundred residents. The sheik
lived in the last named. His dwelling house was constructed of poles planted in the ground, between which wattles were woven and
then plastered with clay. It was thatched, and contained several apartments, one of considerable size, which could be used as a hall
of state. The floor, like that of Bantu huts, was made of ant heaps moistened and stamped. It was covered with mats, and the room
occupied by the sheik was hung with silk, but was poorly furnished according to modern European ideas. This was the grandest
dwelling house in Africa south of the Zambezi, indeed the only one of its size and form, in the first year of the sixteenth century."

There are many links for Mogadishu. Baadiyow will do. Dr Hersi or Scott Reese are better. I will use this one because it is different and because it is brief and to the point.
The Shirazis and Mogadishu:

"By the 5th-6th century AD, trade with East Africa was almost totally monopolised by traders from the Red Sea area and the Persian Gulf. Between 620-1000 AD, Arabs and Persians (especially Shirazis), fleeing from religious conflicts in their countries of origin, settled in East Africa which they called Zanjabar - the Land of the Black People. Most of them belonged to the Sunni Shafe'i sect and when the Shirazis, who were Shi'a came and settled alongside, they put aside their conflicts, learned the local language, and married local Bantu women and converted them. This merger of the customs, religion and languages of these diverse people became the Swahili culture (the word Swahili itself coming from the Arabic sahil meaning coast). The raison d'etre for the success of this civilsation on the East African coast, stretching from Mogadishu in the north to Madagascar and Sofala in the south, was mercantile. It depended on the import of goods from overseas, which were exchanged for those from the mainland, and which in turn were exported to home markets or elsewhere. On the profits of this trade, a solid and comfortable bourgeois society grew and flourished. There were 37 medieval towns along the East African coast built on islands or on the mainland itself. They were never united into one kingdom, as rivalries and differences were frequent occurrences between the settlements. However, the most important towns - Mogadishu, Zanzibar, Kilwa and Sofala - remained the capitals of their respective kingdoms until the advent of the Portuguese in 1488, which drastically altered the balance of power in East Africa."
"Mogadishu The earliest and most important Muslim town in East Africa, already a major trading town by 1000 AD. It was always pre-occupied with its contacts to the Arab world and never interfered in events on the coast further south."
There is no mention of Somalis or Ajuraan.
