Muwatta Malik, Book 22, Hadith 2 (USC-MSA) ⓘ

Yahya related to me from Malik from Abdullah ibn Abi Bakr that his paternal aunt related that her grandmother made a vow to walk to the Quba mosque. She died, and did not fulfill it, so Abdullah ibn Abbas asked her daughter to walk for her. Yahya said that he had heard Malik say, "No one walks for anyone else."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي بَكْرٍ، عَنْ عَمَّتِهِ، أَنَّهَا حَدَّثَتْهُ عَنْ جَدَّتِهِ، أَنَّهَا كَانَتْ جَعَلَتْ عَلَى نَفْسِهَا مَشْيًا إِلَى مَسْجِدِ قُبَاءٍ فَمَاتَتْ وَلَمْ تَقْضِهِ فَأَفْتَى عَبْدُ اللَّهِ بْنُ عَبَّاسٍ ابْنَتَهَا أَنْ تَمْشِيَ عَنْهَا ‏.‏ قَالَ يَحْيَى وَسَمِعْتُ مَالِكًا يَقُولُ لاَ يَمْشِي أَحَدٌ عَنْ أَحَدٍ ‏.‏
