الناس لا ترحم.

A literal translation would be:
Can the druggist repair what time has ruined?
Wa hal yuslihu al-attaru ma afsada ad-dahru
وَهَلْ يُصْلِحُ الْعَطَّارُ مَا أَفْسَدَ الدَّهْرُ
.
.
أحاطَ بهِ [...]

.
This expression literally means “the magic turned against the magician” and it implies some form of karma or poetic justice.

Pronunciation:
Inqalaba as-sihru ala as-sahir
