Bulugh al-Maram

Book 2: The Book of Prayer
زَادَ مُسْلِمٌ: { لَا يَذْكُرُونَ : (بِسْمِ اَللَّهِ اَلرَّحْمَنِ اَلرَّحِيمِ )‏ فِي أَوَّلِ قِرَاءَةٍ وَلَا فِي آخِرِهَا } .‏ 1‏
And Muslim added:

"They would not recite Bismillahir-Rahmanir-Rahim, neither in the beginning of the recitation nor at the end of it."
