عَليكَ الكَتْمَ واحذَرْ قَوْلَ سِرٍّ

لِمَنْ قَدْ ظَلَّ سِرَّ سِواكَ يَحْكي

Concealment is incumbent, beware revealing secrets

To one who has betrayed another's confidence before.

فَمَنْ أهداكَ سِرَّ الغَيْرِ يَوماً

أفادَ الغَيْرَ سِرَّكَ دونَ شَكِّ

Whoever once confided in you another's secret,

Will in turn confide your secrets to that other, doubt not.
