Hadeeth 5: Acts which have not commanded in islam
On the
authority of the mother of the faithful, Aaishah (may Allah be pleased with
her), who said:
The Messenger of Allah (peace and blessings of Allah be upon him) said, “He who
innovates something in this matter of ours [i.e., Islam] that is not of it will
have it rejected [by Allah].”

In one version by Muslim it reads: “He who does an act which
we have not commanded, will have it rejected [by Allah].”
