Some of the lyrics from the beginning of the Nasheed:
How blessed are you by Allaah (SWT)
You were not distracted by wordly frivolities
And you did not run behind
The falsehoods in abandonement
Nor did you (make) dirty your dignified foreheads
By begging from the enemies
You illuminated the darkness
Willingly (by sacrificing yourself)
