I was browsing site of grand ayatolla al-Shirazi. Translator of his answers, added some info from himself in the text. He said:
Some of the Sunni sources, which report this event, are as follows:
- Ibn Hajar al-‘Asqalani, Lisaan al-Meezaan, vol. 1, p 268
- Muhib-id-Deen al-Tabari, Thakha‘er al-‘Uqba, vol. 6, p17
- Al-Shahrestaani, al-Melal wa al-Nahal, vol. 1, p 57
- Al-Mas’udi, Ithbaat al-Waseyyah, p 142
Praise to Allah! Masudi wasn’t sunni. But he was shia, as we have mentioned before.
