“At what hour did the Prophet
(ﷺ) go out on this day?” He said: “When that time comes, we
will go out.” So Hajjah sent a man to watch for the time when they
went out.
When Ibn ‘Umar wanted to set out, he said: “Has the sun passed the zenith?” They said: “It has not passed the zenith yet.” So he sat down. Then he said: “Has the sun passed the zenith?” They said: “It has not passed the zenith yet.” So he sat down. Then he said: “Has the sun passed the zenith?” They said: “Yes.” When they said that it had passed the zenith, he set out.
