#1386 It was
narrated that Ibn ‘Abbas said:
“A Bedouin came to the Prophet
(ﷺ) and said: ‘I have seen the new crescent tonight.’ He said:
‘Do
you bear witness that none has the right to be worshipped but
Allah
and that Muhammad is the Messenger of Allah (ﷺ)?’ He said:
‘Yes.’ He
said: ‘Get up, O Bilal, and announce to the people
that they should
fast tomorrow.’” Abu 'Ali said: "This is how it
was narrated from Walid bin Abu
Thawr and Hasan bin 'Ali. It was
also narrated from Hammad bin
Salamah, but he did not mention
Ibn 'Abbas. He said: 'And he
announced that they should
perform the prayer and that they
should fast.'"
