Concept:The phrase “Alayhs-salam” is an Islamic honorific used after the names of prophets, specifically those other than Prophet Muhammad.
Explanation:In Islamic tradition, “Alayhs-salam” means “peace be upon him”.
This phrase is used when mentioning any prophet except Prophet Muhammad.
For Prophet Muhammad, Muslims use “Sallallahu alayhi wa sallam” instead.
It is also not applied to Maryam or the orthodox caliphs in this context.
Therefore, hearing “Alayhs-salam” indicates that the name of Prophet Ya’qub has just been mentioned.
Answer:B. Prophet Ya’qub has been mentioned.
