Can a Muslim accept a gift from his kaafir brother?

What is the ruling on two brothers, one of whom is a Muslim and the other is a mushrik and rich. Is it permissible for the Muslim brother to accept a gift from his kaafir, mushrik brother, or not?.

Praise be to Allah, and blessings and peace be upon the Messenger of Allah:

It is permissible for a Muslim to accept a gift from his brother if he is a kaafir or a mushrik, because that may soften his heart and Allah may guide him to Islam.

And Allah is the Source of strength.
