The reason I ask is because I want to put the emphasis on the sunnah. If I can quote the hadith or practice it comes from with and include it on a note with the dates, then surely this is 'dhikr' as well as I am trying to spread knowledge to the other guests too? Does that make sense? Yes, we do this practice in Pakistani weddings, but I want to trace where the custom comes from and relate it back to Islam. Any help genuinely appreciated.
