What is the ruling on some people saying, "Do not forget us, my brother, in your supplication"?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: Some people frequently say, "Do not forget us, my brother, in your supplication," to the point that I said to one of them, "It is clear [that this is not appropriate]." He replied to me, "I am in need of your supplication." What is the ruling on this? And what is your response?

Answer:
The Messenger (peace and blessings be upon him) said this to 'Umar when 'Umar intended to travel for 'Umrah. The Messenger (peace and blessings be upon him) said to him, "Do not forget us, my brother, in your good supplication." 'Umar said, "I would not love to have the world and what is in it for this word." There is nothing wrong with you asking your brother to make supplication for you, especially if he is going on 'Umrah or Hajj. You say to him, "Make supplication to Allah for me in your Hajj and in your 'Umrah." There is nothing wrong with this.
