—provided it was no longer travelling in the company of the Prophet ﷺ. In other words, every one of those transactions—and anything else people customarily do with an animal—remained permissible; the sole prohibition concerned its accompanying him ﷺ. All such uses were originally lawful, and he merely excluded one of them while leaving the rest as they were. Allah knows best.

[Commentary]
These reports are cited by al-Nawawī—may Allah have mercy on him—in his Riyāḍ al-Ṣāliḥīn under the heading “The Warning against Invoking Curses.”

One of them is the ḥadīth of Samura ibn Jundub, in which the Prophet ﷺ said: “Do not curse one another by invoking Allah’s curse, His wrath, or the Fire.” That is, none of you should say to his companion, “May Allah curse you,” or, “May Allah’s anger be upon you,” or, “May Allah admit you into the Fire.” The Prophet ﷺ warned against all of this, for a person might direct such words at someone who does not deserve them.

The Prophet ﷺ also said: “A believer is not a reviler, nor a curser, nor obscene, nor indecent.” This shows that these traits diminish one’s faith, stripping a believer of its reality and perfection. Hence a Muslim must not be a fault-finder who attacks people’s lineage, honour, appearance, manner, or aspirations; nor may he be a habitual curser whose constant refrain is, “May Allah curse you—do this; may Allah curse you—do that.” Why would anyone speak like this? Some even say to their own children, “May Allah curse you; bring me that,” and the like.

A believer is neither a person who curses, nor one whose speech is vulgar—raised voices and coarse words—nor foul-mouthed, assaulting others with his tongue. A believer is, by definition, a believer.
