There are brown arab jews. They are semitic and match up with arabs closely. No one else matches up with the supposed cousins and other son's of ibrahim genetically.
Honestly i'm not against this, i'm just not convinced.
This is the mayor of Bosaaso, is he Somali to you? because he certainly doesn't look like the average Somali of today, but if we go back a century he has a closer resembles then you have.
What about the Somali's from just a century ago? do they look like the ones today ?
Variation of looks or even features is not a solid argument, it changes drastically within a century never mind a millennium back.
Let's explore some Islamic sources.
Al-Haakim (8194) narrated that Ibn ‘Umar (may Allah be pleased with him) said: The Prophet (blessings and peace of Allah be upon him) said: “I saw (in a dream) many black sheep who were joined by many white sheep.” They said: How did you interpret it, O Messenger of Allah? He said: The non-Arabs will join you in your religion and your lineage.” They said: The non-Arabs, O Messenger of Allah? He said: “If faith were at the Pleiades, some men from among the non-Arabs would get it.”
Classed as saheeh by al-Albaani in as-Saheehah (1018).
وَاِذۡ تَاَذَّنَ رَبُّكَ لَيَبۡعَثَنَّ عَلَيۡهِمۡ اِلٰى يَوۡمِ الۡقِيٰمَةِ مَنۡ يَّسُوۡمُهُمۡ سُوۡٓءَ الۡعَذَابِ ؕ اِنَّ رَبَّكَ لَسَرِيۡعُ الۡعِقَابِ ۖۚ وَاِنَّهٗ لَـغَفُوۡرٌ رَّحِيۡمٌ
(7:167) And recall when Your Lord proclaimed127 that 'He would continually set in authority over them, till the Day of Judgement, those who would ruthless oppress them.'128 Surely, your Lord is swift in chastising; and yet He is All-Forgiving, All-Merciful.
