Tolong jelaskan mengenai Zal and white hair dari Zal dan Rudabeh

Mehrab returned to the palace and praised Zal's glamorous qualities for his wife Sindukht, but said the gladiator had only one flaw and that he had white hair. Rudaba heard the talk but fell in love with Zal's character and wished he could understand her better. Rudaba was restless like Zal and sent five of her slaves to Zal's tent to get to know each other. Eventually, one night Zal climbed the wall of the palace with Rudaba's escort, and the two lovers' wishes came true. But an acute problem later emerged, and it was the Iran king's opposition to their marriage.
