question #2 Sahih al-Bukhari 6404, Book 80, Hadith 99 : How is the act of manumitting a descendant of Ishmael viewed in Islamic teachings?

Whoever recites it (i.e., the invocation in the above Hadith (412) ten times will be as if he manumitted
one of Ishmael’s descendants. Abu Aiyub narrated the same Hadith from the Prophet (ﷺ) saying,
“(Whoever recites it ten times) will be as if he had manumitted one of Ishmael’s descendants.”
