It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said on the day of the Battle of Ta’if:“If Allah wills, tomorrow we will return.”So the people said:“Will we return without conquering Ta’if?”The Prophet (peace and blessings be upon him) said:“Then go out for battle in the morning!”So they went out for battle in the morning and suffered hardship. Then the Messenger of Allah (peace and blessings be upon him) said:“If Allah wills, tomorrow we will return.”So the people became happy, and the Messenger of Allah (peace and blessings be upon him) smiled.
