We come across numerous interesting “new Interpretations” in the book named “Islam” written by the Director of Islamic Research, Dr. Fazlur Rehman. According to him only three daily Salah were originally made obligatory, and two more were added in the last years of the Prophet’s life. Hence their number has the possibility of accepting changes.
“Anyhow, the fact that basically there were three daily Salah is also supported by the incidence that there is one narration according to which Prophet (PBUH) has converted the four Salah into two”. Anyway it happened in the post-prophetic era that the number of Salah without any alternative choice, was strictly fixed as five. In this way the fact that the number was basically three got swept away in the flood of traditions reported in support of the number of five”. (Monthly “Fikr-o-Nazar, vol: 5, p.259) Read more...
