The ruling on saying "May the Most Merciful be with you" and "May Allah prolong your life"

Question:
The phrase "May the Most Merciful be with you" is used in many matters, especially when asking a person to accept an invitation to a gathering, saying "May the Most Merciful be with you" or similar phrases. What is the ruling on this?

Answer:
This is a supplication that appears to be a prayer asking Allah to be with the person through support, victory, and assistance. For Allah the Exalted says: Indeed, Allah is with us . This presence means victory, support, and encompassing care. So if he says, "May the Most Merciful be with you," it is as if he is praying for him that Allah be with him through His victory, guidance, and assistance. I do not see anything that prevents this. Likewise, if he says, "May Allah keep you alive" or "May Allah prolong your life," or something similar, this is among the permissible things, and there is no harm in it. However, it is good if he says, "May Allah prolong your life in goodness" or "May Allah prolong your life in obedience."
