Volume 8, Book 73, Number 109:
Narrated ‘Abdullah bin ‘Umar:
When Allah Apostle was in Ta’if (trying to conquer it), he said to his companions, “Tomorrow we
will return (to Medina), if Allah wills.” Some of the companions of Allah’s Apostle said, “We will not
leave till we conquer it.” The Prophet said, “Therefore, be ready to fight tomorrow.” On the following
day, they (Muslims) fought fiercely (with the people of Ta’if) and suffered many wounds. Then Al –
lah’s Apostle said, “Tomorrow we will return (to Medina), if Allah wills.” His companions kept quiet
this time. Allah’s Apostle then smiled.
