Muwatta Malik, Book 29, Hadith 1251 (In-Book)

Yahya related to me from Malik from Humayd ibn Qays al-Makki from Amr ibn Shuayb from Said ibn al-Musayyab that Umar ibn al-Khattab sent back widows from the desert and prevented them from doing the hajj.

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ حُمَيْدِ بْنِ قَيْسٍ الْمَكِّيِّ، عَنْ عَمْرِو بْنِ شُعَيْبٍ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، ‏.‏ أَنَّ عُمَرَ بْنَ الْخَطَّابِ، كَانَ يَرُدُّ الْمُتَوَفَّى عَنْهُنَّ أَزْوَاجُهُنَّ مِنَ الْبَيْدَاءِ يَمْنَعُهُنَّ الْحَجَّ ‏.‏
