Muharib bin Dithar (may Allah have mercy on him) said: A Mother of the Believers died, I think it was Sayyidah Maymunah (may Allah be pleased with her), and she left instructions that Sa'id bin Zayd (may Allah be pleased with him) should lead her funeral prayer.
Sufyan al-Thawri narrated it from Ata bin al-Sa'ib, from Muharib bin Dithar, that Umm Salamah (may Allah be pleased with her) left instructions that someone other than the ruler should lead her funeral prayer; and this is more correct.
