وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ حَافَظَ عَلَى شُفْعَةِ الضُّحَى غُفِرَتْ لَهُ ذنُوبه وَإِن كَانَت مثلا زَبَدِ الْبَحْرِ» . رَوَاهُ أَحْمَدُ وَالتِّرْمِذِيُّ وَابْنُ مَاجَهْ

Abu Sa'id said

God’s Messenger used to pray in the forenoon so often that we felt he would never stop doing so; then he would leave off doing so for so long that we felt he would never resume prayer at that time. Tirmidhi transmitted it.
