It was narrated that Qais bin 'Ubad said:

"While I was in the Masjid in the first row, a man pulled me from behind and moved me aside, and took my place. By Allah, I could not focus on my prayer, then when he left I saw that it was Ubayy bin Ka'b. He said: '0 boy, may Allah protect you from harm. This is what the Prophet instructed us to do, to stand directly behind him.' Then he (Ubayy) turned to face the Qiblah and said: 'Doomed are Ah1 Al-'Uqd, by the Lord of the Ka'bah! - three times.'Then he said: 'By Allah, I am not sad for them, but I am sad for the people whom they have misled.' I said: '0 Abu Ya'qub, what do you mean by Ah1 Al-'Uqd?' He said: 'The rulers."'
