Cabdishakuur
In Somali orthography, the letter 'C' represents the Arabic letter Ayn (ع), making this the Somali spelling of Abdushakur.
It means 'Servant of the Thankful,' referring to Al-Shakur, one of the names of Allah meaning the One who appreciates and rewards gratitude.
While originating in Somali, the concept of Abdul Shakur is recognized in Persian Sufi traditions, though the Somali spelling is extremely rare outside the Horn of Africa.
Yes, the divine attribute Al-Shakur (The Thankful/Appreciative) appears in the Quran, such as in Surah Fatir 35:30.
Cabdishakuur is traditionally a masculine name given to boys.
