What does Kalila mean?
An Arabic feminine name linked to the root kh-l-l behind khalil 'close friend, companion, beloved'. Sources give both 'beloved/sweetheart' and 'dear friend'; the 'friend' sense is the more literal core, so treat 'beloved' as the affectionate extension.
What does Sumaya mean?
Sumaya (سمية, Sumayya) is a diminutive whose root is debated: classical research links it to the root w-s-m, giving 'a small distinguishing mark' and figuratively 'unique, special', while other sources derive it from s-m-w ('high, elevated') for a sense of 'exalted'. It is historically revered as the name of Sumayya bint Khayyat, regarded as the first martyr of Islam. Also spelled Sumayya or Sumayyah.
