وَيَشكُرُand Yashkur لاnot تَستَطيعُis able الوَفاءَkeeping faith
وَيَشكُرُ لا تَستَطيعُ الوَفاءَ
وَتَعجَزُand is unable يَشكُرُYashkur أَنto تَعذِراoffer an excuse
وَتَعجَزُ يَشكُرُ أَن تَعذِرا
And Yashkur cannot keep faith.
He thanks but cannot keep his promise
And Yashkur is unable to offer an excuse.
And fails to thank, unable to apologize
