It has been about one thousand and two hundred years that, the book Sunan Abī Dāwūd was compiled.
And for many years, there has been a part named” Kitāb al-Mahdī’” in the fourth chapter of this book.
So all the people who have quoted contents from that part, would refer to the same [Kitāb al-Mahdī]…
But unfortunately when the book Sunan Abī Dāwūd was reprinted in 1408 (AH) in Egypt
, the name Kitāb al-Mahdī was changed into Kitāb al-Hodā!!
