By Shaykh Abdul Fattah Abu Ghuddah (Translation by Qays Arthur)
Now some people wrongfully allege, without properly grasping the texts nor giving them their due, that the Sunnah is to begin with whomever is to the immediate right of the host based on the hadiths that mention the virtue of beginning on the right.
Yet that only pertains to when those present are peers with respect to their traits, virtues, or age. In that case the host begins with whomever is to his right. Otherwise if one of the guests is distinguished from the others, by age for example, then one would begin with him by virtue of that noble trait.
