A: The method of Khatams in vogue are not proven from the Sunnah, nor was it the system of the noble Sahaabah Kiraam (Radhiyallaahu Anhum). Thus, it is best not to participate in such Khatam gatherings, though it is permissible to do so. One should not regard these gatherings as Sunnah, nor so necessary, that those who don't participate in them are condemned and criticized. As far as Riya is concerned, it depends on the intention of the individual.
