`Aisha said If the Prophet (ﷺ) saw a cloud In the sky, he would walk to and fro in agitation, go out and
come in, and the color of his face would change, and if it rained, he would feel relaxed." So `Aisha
knew that state of his. So the Prophet (ﷺ) said, I don't know (am afraid), it may be similar to what
happened to some people referred to in the Holy Qur'an in the following Verse: -- "Then when they
saw it as a dense cloud coming towards their valleys, they said, 'This is a cloud bringing us rain!' Nay,
but, it is that (torment) which you were asking to be hastened a wind wherein is severe torment."
(46.24)
Sahih al-Bukhari Book 59, Hadith 17
Yahya related to me from Malik that Yahya ibn Said said, "The
Messenger of Allah, may Allah bless him and grant him peace, had
wanted to take two pieces of wood to strike them together to gather
people for the prayer, and Abdullah ibn Zayd al-Ansari, then of the
tribe of Harith ibn al-Khazraj, was shown two pieces of wood in his
sleep. He said, 'These are close to what the Messenger of Allah, may
Allah bless him and grant him peace, wants.' Then it was said, 'Do
you not call to the prayer?', so when he woke up he went to the
Messenger of Allah, may Allah bless him and grant him peace, and
mentioned the dream to him. The Messenger of Allah, may Allah bless
him and grant him peace, ordered the adhan."
