Amr bin Abasa reported,

He said, "Prophet of Allah, tell me about what Allah has taught you and which I do not know. Tell me about the prayer."He replied, "Pray the dawn prayer, then refrain from prayer until the sun rises and climbs high, for it rises between the two horns of Satan, and at that moment the disbelievers prostrate to it. After that, pray, for the prayer is witnessed and attended."

Sahih

عن عمرو بن عبسة السلمي قال

يا نبي الله أخبرني عما علمك الله وأجهله، أخبرني عن الصلاة؟ قال: صل صلاة الصبح، ثم أقصر عن الصلاة حتى تطلع الشمس حتى ترتفع، فإنها تطلع حين تطلع بين قرني شيطان وحينئذ يسجد لها الكفار، ثم صل، فإن الصلاة مشهودة محضورة.
