Imām Mālik Ibn Anas (d. 179H) warns a man from going the extra mile beyond the Prophet’s Sunnah ―Innovations (Bid’ah)

A man asked the Imām of Dār al-Hijrah (i.e. Madinah) Mālik Ibn Anas (رحمه الله): “From where should I take the Ihrām for pilgrimage?” Imām Mālik responded: “From wherever the Prophet (‎ﷺ‎‬) took the Ihrām.” The man repeated himself a few times until he said: “So what if I add to that [place of Ihrām an extra distance]?” Mālik said: “Don’t do that, for I fear for you fitnah.” The man said: “What is there in this of fitnah? It is only a matter of miles I am adding to the place of Ihrām?!” Mālik said: “Indeed Allāh, the Most High, said: ‎’Let those beware, who oppose the command of the Messenger lest some fitnah befalls them or a painful punishment is inflicted upon them.’* [An-Noor: 63]“
