Shekau made the comment while speaking in a video released on Sunday, September 25.
“Buhari you are worshiping cows, you better worship Allah. You think you are a general in the Army but you should know that Allah have said that you are not up the house of a spider in his eyes,” Shekau said in the video according to Vanguard.
“What we believe in is the Quran and we do not know anything apart from that. Anytime we say Allah all of you will not live in peace. It is Allah that we believe and trust that makes us live till this day and doing very well in our quest.
“Buhari, all your actions are fake. You are lying to the people, collecting their money and saying you will free their children and you know you are lying. Buhari, Buhari, your people will soon betray you for all this lies.
“I am talking to you Buhari, sit back and think carefully. It is not this small Shekau that is disturbing you. No. It is Allah that is doing everything for us, continue and see. You deceived the people and you think you are doing the right thing.
“Continue and see, one day you will not even be able to go to the toilet and stool. But if you repent, then you are a brother. Repent and follow the Quran. “Buhari let me advise you now, fear Allah,” he added.
Shekau released the video in a bid to dismiss claims by the Nigerian military that he was fatally injured in an air raid in August.
