Haaroon ibn Abd Allah narrated to me, Hajjaaj ibn Muhammad narrated to us, from Ibn Juraij, Musa ibn Uqbah informed me, from Naafi’, he said: I heard Abdullah ibn Umar say: The Messenger of Allah, peace and blessings be upon him, said: "Respond to this invitation when you are invited to it." He said: And Abdullah ibn Umar used to attend the invitation for a wedding and other than a wedding, and he would attend it while he was fasting.
