Ustaadh Abu Iyaad Amjad Rafiq uses the concise explanation of Sheikh Saalih al Fawzaan of Hadith of Jibreel.
This is a comprehensive hadith which describes an important event when the Angel Jibreel came to the Prophet, peace be upon him, asking questions which the whole Ummah can benefit from. From this, we learn about the five pillars of Islam, the pillars of Eeman and the definition of Ihsaan. The speaker expands on these categories, giving a brief summary of each.
The hadith also gives a beautiful description of one of the ways Jibreel appeared to the Prophet, peace be upon him. Apart from important fundamentals of our aqeedah (belief) there are also other benefits which can be found, including learning some of the manners of seeking knowledge.
It is also mentioned that the Salaf (pious predecessors) differentiated between Imaan and Islam, further details of this are discussed in this talk. To understand this further, listen to the audio.
All of this is part of his series of classes which goes through the Forty Hadeeth of Imam An-Nawawi, a compilation of hadeeth which all issues of the of the shariah revolve around.
