Hadith 504410
Chapter 10: The Two 'Ids - كتاب العيدين
وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ سَعِيدَ بْنَ الْمُسَيَّبِ، كَانَ يَغْدُو إِلَى الْمُصَلَّى بَعْدَ أَنْ يُصَلِّيَ الصُّبْحَ قَبْلَ طُلُوعِ الشَّمْسِ .
Yahya related to me from Malik that he had heard that Said ibn al-Musayyab used to go to the place of prayer after praying subh, and before the sun rose.
