used without being paired (1) with ghudūw (setting out in the morning). Al-Azharī said (2) in al-Tahdhīb (3): “I have heard the Arabs use rawāh for travelling at any time. They say, ‘Rāha al-qawm (the people set out),’ when they travel or depart in the morning. One says to his companion, ‘Tarawwah (set out),’ and addresses his companions by saying, ‘Rūhū (go forth).’ Another says, ‘Will you not set out?’ Similar expressions occur in sound, established reports, where they mean proceeding to the Friday prayer and hastening to it, not setting out in the late afternoon.” (4)
As for the terms tahjīr, hajīr (5), and muhajjir, they derive from hajr (6) and hājira. Al-Jawharī said (7): “It is midday, when the heat is intense.” From this one says, “Hajjara al-nahār (the day has reached its midday heat).” Imruʾ al-Qays said (8):
Leave her, and banish sorrow for her on a sturdy she-camel,
Swift and smooth of gait, when the sun stands overhead and midday blazes.
