Musnad Abu Ya'la al-Mawsili 209:135

Abu Khaythama narrated to us, Ubayd Allah ibn Musa narrated to us, Isa ibn Abd al-Rahman al-Bajali narrated to us, from al-Suddi, from Abu Abd Allah al-Jadali, who said: Umm Salama said: "Is the Messenger of Allah, may Allah bless him and grant him peace, being insulted upon the pulpits?" I said: "And how is that?" She said: "Is Ali and whoever loves him not being insulted? And I bear witness that the Messenger of Allah, may Allah bless him and grant him peace, used to love him."
