وَمَا كَانَ لِمُؤْمِنٍۢ وَلَا مُؤْمِنَةٍ إِذَا قَضَى ٱللَّهُ وَرَسُولُهُۥٓ أَمْرًا أَن يَكُونَ لَهُمُ ٱلْخِيَرَةُ مِنْ أَمْرِهِمْ ۗ وَمَن يَعْصِ ٱللَّهَ وَرَسُولَهُۥ فَقَدْ ضَلَّ ضَلَٰلًۭا مُّبِينًۭا
And it becometh not a believing man or a believing woman, when Allah and His messenger have decided an affair (for them), that they should (after that) claim any say in their affair; and whoso is rebellious to Allah and His messenger, he verily goeth astray in error manifest.
Surah Al-Ahzaab(33:36)

Times of the Prayers
Chapter: What is said regarding the offering of As-Salat (the prayers) between the Fajr prayer and sunrise.
Narrated Abu Huraira:
Allah's Messenger (ﷺ) 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).
