Hadith 507490
Chapter 20: Hajj - كتاب الحج
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ جَعْفَرِ بْنِ مُحَمَّدٍ، عَنْ أَبِيهِ، أَنَّ عَلِيَّ بْنَ أَبِي طَالِبٍ، كَانَ يُلَبِّي فِي الْحَجِّ حَتَّى إِذَا زَاغَتِ الشَّمْسُ مِنْ يَوْمِ عَرَفَةَ قَطَعَ التَّلْبِيَةَ . قَالَ يَحْيَى قَالَ مَالِكٌ وَذَلِكَ الأَمْرُ الَّذِي لَمْ يَزَلْ عَلَيْهِ أَهْلُ الْعِلْمِ بِبَلَدِنَا .
Yahya related to me from Malik, from Jafar ibn Muhammad, from his father, that AIi ibn Abi Talib used to say the talbiya while on hajj until after noon on the day of Arafa, when he would stop doing so. Yahya said that Malik said, "This is what the people of knowledge in our city are still doing."
