"I heard the Messenger of Allah inviting people to have Sahur in Ramadan. He said: 'Come to the blessed breakfast." (Hasan) Chatper 26. Calling Sahur "Ghada" (Breakfast) (Using translation from Nasāʾī 2163)  

سَمِعْتُ رَسُولَ اللهِ ﷺ وَهُوَ يَدْعُو إِلَى السَّحُورِ فِي شَهْرِ رَمَضَانَ فَقَالَ «هَلُمُّوا إِلَى الْغَدَاءِ الْمُبَارَكِ»
