Qa'aqa then took up the question of promoting the cause of Islam. He pointed out that when the Muslims were united under Abu Bakr and Umar they made large conquests both in the east and the west. In the early years of the caliphate of Othman the process of conquests continued. When the Muslims rebelled against the authority of Othman, and came to be divided among themselves the process of conquest came to a grinding halt. He observed that the enemies of Islam were on the borders of the Muslim State ready to take advantage of any division in the ranks of the Muslims. Qa'aqa posed the question, "How can you promote the cause of Islam, if you seek to divide the Muslims for one cause or the other?" Addressing the confederates he asked, "Did you promote the cause of Islam when you killed six hundred men of Basra, and the mosque was dyed with blood? Did you thereby avenge the murder of Othman when such persons were not even remotely connected with the murder of Othman? If you killed them because rightly or wrongly you suspected them of being involved in the assassination of Othman, then is your demand for the 'Qasas' for the blood of Othman not yet satisfied?" Then he respectfully addressed Ayesha saying: "O Mother of the Faithful! Did God not enjoin you to sit quietly in your home? Did the Holy Prophet warn you that the dogs of Hu'ab would bark on you? Then how did you promote the cause of Islam by violating these instructions?" Addressing Talha and Zubair he said "Did you not take the oath of allegiance to Ali? If you took the oath of allegiance to Ali under some compulsion, tell us the man for whom you would have voted if you were free. Is any man more qualified, and more worthy to be the Caliph of the Muslims than Ali? Verily Ali is the best man to be the Caliph of the Muslims, and by putting difficulties in his way you do not promote the cause of Islam, you do great harm to Islam."
