Umaru Yar'Adua, the Nigerian president, has returned home after a 93-day absence while seeking medical treatment in Saudi Arabia.<br /><br />But he has not been seen or heard in public since he returned to Nigeria a week ago, serving to fuel speculation about the state of his health.<br /><br />Zubaru Ali is the president's first cousin and one of the few members of the Yar'Adua's family willing to discuss the president's health.<br /><br />Al Jazeera's Yvonne Ndege travelled to Katsina state in northern Nigeria for this interview.
