Prophet asked him, "Have you got camels?" The man said, "Yes." The Prophet (ﷺ) asked him, "What
color are they?" The man replied, "Red." The Prophet (ﷺ) said, "Is there a grey one among them?' The
man replied, "Yes." The Prophet (ﷺ) said, "Whence comes that?" He said, "May be it is because of
heredity." The Prophet (ﷺ) said, "May be your latest son has this color because of heredity."
