Relation of the hadiths that are known as ?hadith qudsî? with the holy texts (Old- New testament)

About the source of hadiths, that are known as `Hadith Qudsî? in literature, there are different opinions and these opinions, basically based on the two agreements as the source of these hadiths is revelation or not.In literature, Hadith Qudsî is defined as a revelation but this definition had arised lately; because of this, it?s thougt that these hadiths had not meaned as revelation in early times.If it?s accepted that Hadith Qudsî is not revelation, another different opinions are discussed and one of them is that this hadiths had quoted from the old holy boks ?the books of the Jewishs and Christs-.To claim that these hadiths were quoted from the books of Jewishs and Christs, at first, we must know that the conditions of Hz. Muhammed were suitable or not. And we must learn about the attitude of Hz. Muhammed to the Jewishs, Christs and their books.In this study, we needed to give place to the factors because of the relation between the different cultures/ religions and Hz. Muhammed/ his society. And we needed to attainThe Jewishs and The Christs in Hz. Muhammed?s society and effects of them. Then we considered necessary to the attitude of Hz. Muhammed to these foreign people and their books. So, we appropriated the firs and the second parts to these themes.The third part is concerned the knowledge of Hz. Muhammed about the other books and the examples of similar Hadith Qudsi and the Old- New Testament texts, sign to a relation between them.Consequently, as we pay attension to the relation and attitude of Hz. Muhammed and his society with this foreign cultures and religions, the opinion as the `Hadith Qudsi?s are quoted from another books is seem sensible, considerable and needs more studies.Key Words: 1) Hadith Qudsî, 2) Old Testament, 3) New Testament.
