THE EMIGRATING SEPTS OF KAHLAN CAN BE INTO FOUR GROUPS:
1. Azd: Who, under the leadership of ‘Imran bin ‘Amr Muzaiqbâ’, wandered in Yemen, sent pioneers and finally headed northwards. Details of their emigration can be summed up as follows:
2. Tha‘labah bin ‘Amr left his tribe Al-Azd for Hijaz and dwelt between Tha‘labiyah and Dhi Qar. When he gained strength, he headed for Madinah where he stayed. Of his seed are Aws and Khazraj, sons of Haritha bin Tha‘labah.
Haritha bin ‘Amr, known as Khuza‘a, wandered with his folks in Hijaz until they came to Mar Az-Zahran. Later, they conquered the Haram, and settled in Makkah after having driven away its people, the tribe of Jurhum.
‘Imran bin ‘Amr and his folks went to ‘Oman where they established the tribe of Azd whose children inhabited Tihama and were known as Azd-of-Shanu’a.
Jafna bin ‘Amr and his family, headed for Syria where he settled and initiated the kingdom of Ghassan who was so named after a spring of water, in Hijaz, where they s topped on their way to Syria.
2. Lakhm and Judham: Of whom was Nasr bin Rabi‘a, father of Manadhira, Kings of Heerah.
3. Banu Tai’: Who also emigrated northwards to settle by the so- called Aja and Salma Mountains which were consequently named as Tai’ Mountains.
4. Kinda: Who dwelt in Bahrain but were expelled to Hadramout and Najd where they instituted a powerful government but not for long , for the whole tribe soon faded away.
Another tribe of Himyar, known as Quda‘a, also left Yemen and dwelt in Samawa semidesert on the borders of Iraq.
