Seeing fetters in a dream signifies steadfastness in religion

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "In the last age, the dream of a believer will hardly ever be false, and the most truthful of you in dreams will be the one who is most truthful in speech. Dreams are of three kinds: a good dream, which is glad tidings from Allah, the Mighty and Majestic; a dream in which a person's own self talks to him (his thoughts); and a dream from Satan meant to cause grief. So when one of you sees a dream that he dislikes, he should not relate it to anyone; rather he should get up and pray. And the dream of a believer is one part of the forty-six parts of prophethood." Sayyiduna Abu Hurayrah (may Allah be pleased with him) used to say: "I like to see a fetter (on the feet) in a dream and I dislike a shackle (around the neck), because the fetter signifies steadfastness in the religion."
This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it with this wording.

It is narrated from Sayyiduna Abu Razin al-Uqayli (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "The dream of a believer is one part of the forty-six parts of prophethood, and it is upon the leg of a bird as long as it is not related; then when it is related, it comes to pass."
This hadith has an authentic (sahih) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it with these additional words.
