This video, with English subtitles, explains a term Muslims (today) love to throw around like candy: Bid’ah. Unfortunately, we do not understand how serious this term is, and so, take a seat and listen to the Grand Mufti of Egypt Ali Gomaa.
Some really important points raised in this video which re-emphasise the issue of understanding the principles of Islam rather than just learning the rituals and implementing those dogmatically without consideration for the flexibility that Islam allows.
