Sahih al-Bukhari Hadith 7112

When Ibn Ziyad and Marwan were in Sham and Ibn Az-Zubair رضی اللہ عنہ took over the authority in Mecca and Qurra' (the Kharijites) revolted in Basra, I went out with my father to Abu Barza Al-Aslami رضی اللہ عنہ till we entered upon him in his house while he was sitting in the shade of a room built of cane. So we sat with him and my father started talking to him saying, "O Abu Barza! Don't you see in what dilemma the people has fallen?" The first thing heard him saying "I seek reward from Allah for myself because of being angry and scornful at the Quraish tribe. O you Arabs! You know very well that you were in misery and were few in number and misguided, and that Allah has brought you out of all that with Islam and with Muhammad till He brought you to this state (of prosperity and happiness) which you see now; and it is this worldly wealth and pleasures which has caused mischief to appear among you. The one who is in Sham (i.e., Marwan), by Allah, is not fighting except for the sake of worldly gain: and those who are among you, by Allah, are not fighting except for the sake of worldly gain; and that one who is in Mecca (i.e., Ibn Az-Zubair رضی اللہ عنہما ) by Allah, is not fighting except for the sake of worldly gain."
