Al-Muwatta de Malik, 514

Ourwa a rapporté que l'Envoyé d'Allah (salallahou alayhi wa salam) r (Sur lui la grâce et la paix d'Allah) disait: «Lorsque le rond solaire commence à faire son apparition, retardez la prière jusqu'à son apparition complète; et lorsque le cadran solaire est à sa disparition, retardez la prière jusqu'à sa complète disparition»

Yahya related to me from Malik from Hisham ibn Urwa that his father said that the Messenger of Allah, may Allah bless him and grant him peace, used to say, "Delay the prayer when the edge of the sun appears until it is completely in view, and delay the prayer when the edge of the sun is disappearing until it has completely disappeared
