Muwatta Malik, Book 28, Hadith 55 (USC-MSA) ⓘ

Yahya related to me from Malik from Rabia ibn Abd ar-Rahman that al-Qasim ibn Muhammad and Urwa ibn az-Zubayr gave the same judgement to al-Walid ibn Abd al-Malik in the year of his arrival in Madina except that al-Qasim ibn Muhammad said that he divorced his wife on various occasions. (i.e. not at one time).

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ رَبِيعَةَ بْنِ أَبِي عَبْدِ الرَّحْمَنِ، أَنَّ الْقَاسِمَ بْنَ مُحَمَّدٍ، وَعُرْوَةَ بْنَ الزُّبَيْرِ، أَفْتَيَا الْوَلِيدَ بْنَ عَبْدِ الْمَلِكِ عَامَ قَدِمَ الْمَدِينَةَ بِذَلِكَ غَيْرَ أَنَّ الْقَاسِمَ بْنَ مُحَمَّدٍ قَالَ طَلَّقَهَا فِي مَجَالِسَ شَتَّى ‏.‏
