There was no mention of Habar Makador or Dir that I am aware of, though I have seen a Habar Maqdi, those were bandits who refused to pay Zakat and were punished by Al Gazi, some of the translations from the original Arabic hypothesis Habar Maqdi = Habar Makadour. The link is strenuous at best.
You clearly haven't read the commentaries on the Futuh, I'm sure of that. Otherwise you wouldn't have made those comments. Most historians mention the Dir as being the most active participants. The Dir clans participation is without doubt the most verified. Unless, you wish to use as your only source, an Arabic script, which when you transliterate, it can go different ways. Your friend Ramzy disputed the Harti account based on one letter. Now I don't know if that was due to his own prejudice or something else. Either way, the best way to go are those who analyse beyond the Arabic lexicons. How many Isaaq are called Habar Magaadle today? And i've read some of the Arabic manuscripts of Futuh, I did'nt tell you before but some are spelt in different ways.
In regards to Habr Makadi, according to I.M Lewis (whom you yourself quote many times), they are Habr Makadur.
If you find another clan who live near the Geri who have the name called habr Makadi, other than Habr Makadur, let me know in all sincerity.
As for the Dir, then nobody could deny their No.1 role.
Musa Cabdallah, Makadur, Samaroon
^^Gurgurah Dir, mentioned. Futuh, page 123.
Also, in this version, it spells it correctly:
Among the Somali tribes there was another called Habr Makador, from which the Imam had demanded the alms tax. They refused to pay it, escorting to banditry on the roads and actomg evilly towards his country.
Futuh al Habasha, Shihab ad Din Ahmad ibn Abdel Qadir, (16th century) page 27.
You have to realise Arabic is a foreign language in the Horn. Whenever your translating you will corrupt the words, imagine transliteration into English, it will come out worse. These are examples of Hebrew turned Arabic then Latinised.
Gabriel = Jibril
Michael = Mikaaiil
Joshua = Yusha'
Joseph = Yusuf
Peter = Boutros
The only clan that lives near the Geri that fits the description is Habr Makadur. Nobody else.
