Necessity of paying attention to hadith and the sciences related to it

The early scholars – in addition to reading and collating the hadith books – have strived when transmitting the hadiths to indicate the valid spelling and vocalization of the words and to transmit them to others correctly.  In the modern age, however, despite the fact that we feel a great amount of attention to the editing of the works of early scholars, but in most of the cases of editing, enough attention is not paid to valid spelling and vocalization of the words.
On the other hand, one should regard – when editing a hadith book - the transmission of that hadith in other sources so that the difficulties that usually occur in comprehension of hadiths, would be minimized as much as possible. This writing has mentioned instances of the abovesaid difficulties.
