as for almuhammarah it was said that they were from qubabah because they dyed their clothes red during the days of babak and wore them and that was their slogan. it was also said that the reason for this was that they decided that everyone who disagreed with them from the sects and people of truth was himyar and the most correct interpretation is the first one.
وأما المحمرة فقيل انهم لقبوابه لانهم صبغواالثياب بالحمرة ايام بابك ولبسوها وكان ذلك شعارهم وقيل سببه انهم يقررون ان كل من خالفهم من الفرق واهل الحق حمير والاصح هو التأويل الاول
