Muwatta Malik, Book 20, Hadith 181 (USC-MSA)

Yahya related to me from Malik from Yahya ibn Said from Ata ibn Abi Rabah that a mawla of Asma bint Abi Bakr told him, "We arrived at Mina with Asma bint Abi Bakr at the end of the night, and I said to her, 'We have arrived at Mina at the end of the night,' and she said, 'We used to do that with one who was better than you.' "

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ عَطَاءِ بْنِ أَبِي رَبَاحٍ، أَنَّ مَوْلاَةً، لأَسْمَاءَ بِنْتِ أَبِي بَكْرٍ أَخْبَرَتْهُ قَالَتْ، جِئْنَا مَعَ أَسْمَاءَ ابْنَةِ أَبِي بَكْرٍ مِنًى بِغَلَسٍ - قَالَتْ - فَقُلْتُ لَهَا لَقَدْ جِئْنَا مِنًى بِغَلَسٍ ‏.‏ فَقَالَتْ قَدْ كُنَّا نَصْنَعُ ذَلِكَ مَعَ مَنْ هُوَ خَيْرٌ مِنْكِ ‏.‏
