to address them in their own language (1). Allah therefore sends a messenger who speaks their language so that they may understand (2) what he conveys. Thus, the mention here of his companionship with them conveys kindness and beneficence toward them.
This differs from describing someone as his companion, as in the words of Allah Most High:
“Do not grieve; indeed, Allah is with us.”
And the words of the Prophet—may Allah bless him and grant him peace:
“Do not revile my Companions. By Him in whose hand is my soul, if any of you were to spend gold equal to Mount Uhud, it would not equal a mudd given by any one of them, nor even half of it.” (3)
And his words:
“Will you leave my companion alone for my sake?” (4)
And other statements of this kind.
For describing someone as his companion, whether in his own speech (5) or in the speech of Muslims, implies companionship marked by loyalty to him. This is possible only through faith in him. Thus, the expression “his companion” is not applied to someone who accompanies him on a journey while disbelieving in him.
The Quran says concerning him:
“When he said to his companion, ‘Do not grieve; indeed, Allah is with us.’” [Surah al-Tawbah: 40]
The Messenger thus stated that Allah was with him and with his companion. This being with them entails help and support. Allah helps him against his enemy, and every disbeliever is his enemy; it is therefore impossible for Allah to support both him and his enemy together. Were Allah with his enemy, that would cause grief and dispel tranquillity. It is therefore clear that the expression “his companion” denotes companionship marked by allegiance and love, which necessarily entails believing him and believing in him.
