عَلَوْنَ بِأَنْماطٍ عِتَاقٍ وَكِلَّةٍ وِرَادٍ حَوَاشِيهَا مُشَاكَهَةِ الدَّمِ
Their litters were adorned with fine patterned coverings and a curtain whose reddish borders resembled the color of blood.
Anmāṭ ʿitāq describes fine patterned textile coverings; killah is a screen or light curtain associated with the litter. Their ḥawāshī, the borders, are reddish. The comparison mushākahat al-dam is a color simile, not a reference to an episode of violence.
Cloth, color, and motion combine: at a distance the passing litters can be recognized by the fine coverings and their red edging.
