Adil Al-Kalbani, the former Imam of the Haram of Mecca, is from the pure Arab tribe of Bani Kalbaan. Bani Kalbaan are descended from Kulaib Wail and then from Taghlib the son of Wa'il the son of Qaasit the son of Hanib the son of Afsa the son of Da'ami the son of Judaila the son of Asad the son of Rabi'a the son of Nizaar the son of Ma'ad the son of Adnan.

This is the origin of Adil Al-Kalbani. However, look at how he is described by people today. Read what is said about him
here. Also read what is said about him in the comments
here. Read this comment
"...In Riyadh, Saudi one of the best Imaams, if not the best in Riyadh,
is Imaam Adil al-Kalbani, who is originally and ethnically African (his
grand-parents are Omani of African origin) but an Arab
(linguistically)." here. Read about how his features are described as "African"
here.
As I've said, Adil Al-Kalbani is descended from the Taghlib. Read about the tribe
here. Taghlib is the son of
Wa'il the son of Qaasit. As I will show now, the well-known Imam Ahmed ibn Hanbal is also descended from
Wa'il the son of Qaasit. He is Ahmad the son of Mohamed the son of Hanbal the son of Hilal the son of Asad the son of Idris the son of Abdellah the son of Hayyan the son of Abdellah the son of Anas the son of Awf the son of Qasit the son of Mazin the son of
Shaibaan the son of Dhahal the son of Tha'laba the son of Ataaba the son of Sa'ab the son of Ali the son of Bakr the son of
Wa'il the son of
Qaasit the son of
Hanib the son of
Afsa the son of
Da'ami the son of
Judaila the son of
Asad the son of
Rabi'a the son of
Nizaar the son of
Ma'ad the son of
Adnan. His mother is also from the above-mentioned tribe of
Shaibaan (descendants of
Wa'il the son of
Qasit). Read about Ahmad ibn Hanbal
here.
As you can see, Adil Al-Kalbani's tribe - the Bani Kalban - and Imam Ahmad ibn Hanbal are from the same descent. We see the above picture of Adil Al-Kalbani. Let's now read the description of Imam Ahmad ibn Hanbal. Imam Al-Dhahabi says in his book
Siyar A'laam Al-Nubalaa:
"Ibn Duraiy Al-'Akbari said: 'I searched for Ahmad ibn Hanbal (and then found him) and gave him my salaams and he was a tall,
black-skinned man with a dyed beard'". Like Imam Ahmad ibn Hanbal, Adil Al-Kalbani is also a tall, black-skinned man. Why are people describing Adil Al-Kalbani as a person with "African features". I'm sure that people didn't describe Imam Ahmad ibn Hanbal as "African". Do you see how people today have lost knowledge of what a pure Arab looks like?
