(30) CHAPTER. What is said regarding the offering of As-Salat (the prayers) between the Fajr prayer and sunrise.
Narrated Abu Huraira: Allah's Apostle forbade two kinds of sales, two kinds of dresses, and two prayers. He forbade offering prayers after the Fajr prayer till the rising of the sun and after the `Asr prayer till its setting. He also forbade Ishtimal-Assama [??] and al-Ihtiba in one garment in such a way that one's private parts are exposed towards the sky. He also forbade the sales called Munabadha and Mulamasa. (See Hadith No. 354 and 355 Vol. 3).
