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 Bushra mean?
Bushra (بشرى, bushra) means 'good news, glad tidings', from the Arabic root b-sh-r. The same root gives the verb 'to bring good news' and appears in the Quran.
