ضَيّعتَyou forfeited حَقّكَyour right فيthrough لفظٍa word أَتَيتَyou came بِهwith it
ضَيّعتَ حَقّكَ في لفظٍ أَتَيتَ بِه
فَلَوso if سَكَتَّyou had kept silent فَإنَّthen indeed الحقَّthe right كانَwould have been لَكاyours
فَلَو سَكَتَّ فَإنَّ الحقَّ كانَ لَكا
You forfeited your right through a word you uttered.
You have lost your right in an utterance you have made
For had you kept silent, the right would have been yours.
If only you had kept silent, for the right would still be yours
Sol 6.1
