(23) باب فِي إِفْرَادِ الْحَجِّ
Narrated Sa'id ibn al-Musayyab:
A man from the Companions of the Prophet (ﷺ) came to Umar ibn al-Khattab (may Allah be pleased with him). He bore witness before him that when he (the Prophet) was suffering from a disease of which he died he heard the Messenger of Allah (ﷺ) prohibiting performing of umrah before hajj.
