During a most enjoyable speech about the story of Angel Gabriel (YouTube link), Omar Suleiman talks about the three angels visiting Prophet Abraham on their way to annihilate the people of Prophet Lot. (Beginning at around 47m:55s) (In Quran the story is briefly mentioned more than once. The most detailed section (to my extremely limited knowledge) is 11:69-77.)
Omar Suleiman gives a rather detailed account of the story. He barely mentions some sources, but I cannot find them. Where can I find it?
Further, at around 53m:40s, Omar Suleiman mentions that the angels stated: "Your Lord is Most Wise (al-Hakeem) and Most Knowledgeable (al-Aleem)." What is interesting is that, as Omar Suleiman also points out, in Quran the order is always the other way round. (Omar Suleiman also gives the reasoning and wisdom behind this reversal of order.) Is this part also included in the sources that I am looking for?
