As mentioned in the narrations, the messenger of Allah (pbuh) used to recite some prayers known as opening prayers such as Subhaneke, Wejjehtu and Allâhümme Bâid before reciting Fatiha surah while starting the obligatory and supererogatory worships (salat). In this study, it is aimed to find out the reflections of the abovementioned prayers in narrations, and to determine their authenticity and to reveal the reasons why jurisprudential sects preferred different prayers. Benefitting from literature review method, hadith inferences were made, and moving from the books of refutation & corrections and biographies, the cases of the narrators of the hadiths, who took part in the ascription of the narrations, were put forth. After the investigation, it was determined that the narrated narrations about Subhaneke, an opening prayer, were found to have been narrated by eight different prophet companions in their later works through Aisha and Abu Sâ’id al-Khudrî in early hadiths resources; and that all these narrations were week in terms of authenticity. However, it was revealed that the most authentic narrations about the issue were those depending on the practice of Umar. In the hadith resources, it was seen that five different prophet companions narrated some narrations about the Wejjechtu prayer, and that the great majority of these narrations were through Ali, and that most of these narrations were authentic, yet only one reference was found to be weak. On the other hand, it was revealed that the narrations narrated by Abu Huraira between the opening prayer, Allâhümme Bâid, turned out to be genuine in terms of authenticity. For instance, while Hanafis and Hanbalis have preferred reciting Subhaneke during salat, Shafiîs have found it appropriate to recite the prayer Wejjectu in the salat. On the other hand, Malikis have thought that it was obligatory to start the salat with Surah Fatiha, and that it was makruh to recite these prayers in salat.
