“Allahu Akbar, Allahu Akbar, Ashhadu an la
ilaha
illallah, Ashhadu anna Muhammadan Rasulullah (Allah is the Most
Great,
Allah is Most Great, I bear witness that none has the right to
be
worshipped but Allah, I bear witness that Muhammad is the
Messenger of
Allah).” Then he (Ibn ‘Abbas) said: “Proclaim to
the people that they
should pray in their houses.” The people said
to him: “What is this
that you have done?” He said: “One who is
better than me did that. Are
you telling me that I should bring the
people out of their houses and
make them come to me wading through
the mud up to their knees?”
Sunan Ibn Majah Book 5, Hadith 137
