TODAY'S HADITH

It was narrated on the authority of Abu Najih al-Irbad bin
Sariyah (ra) who said:
"The Messenger of Allah (sas) delivered an admonition that
made our hearts fearful and our eyes tearful. We said, "O
Messenger of Allah, it is as if this were a farewell sermon, so
advise us." He said, "I enjoin you to have Taqwa of Allah and
that you listen and obey, even if a slave is made a ruler over
you. He among you who lives long enough will see many
differences. So for you is to observe my Sunnah and the
Sunnah of the rightly-principled and rightly-guided
successors, holding on to them with your molar teeth.
Beware of newly-introduced matters, for every innovation
(bid'ah) is an error."
(Abu Dawud & Al-Tirmidhi, who says it is an authentic hadith
- hasan saheeh)
