وَهاand here هُوَhe يَرجوhopes for فيin غَدٍtomorrow وَعدَthe promise يَومِهِhis day
وَها هُوَ يَرجو في غَدٍ وَعدَ يَومِهِ
لَعَلَّperhaps غَداًtomorrow يَأبىwill refuse لِمُنتَظِرٍto one who waits عُذراan excuse
لَعَلَّ غَداً يَأبى لِمُنتَظِرٍ عُذرا
And here he is, hoping tomorrow will fulfill his day's promise;
Perhaps tomorrow will deny an excuse to one who waits.
