What extraordinary event happened when the Prophet Muhammad (saw) visited Qarnath-Tha-alib in response to the tribulations faced by his people?
 Narrated `Aisha:                     That she asked the Prophet , 'Have you encountered a day harder than the day of the battle) of Uhud?" The Prophet replied, "Your tribes have troubled me a lot, and the worse trouble was the trouble on the day of 'Aqaba when I presented myself to Ibn `Abd-Yalail bin `Abd-Kulal and he did not respond to my demand. So I departed, overwhelmed with excessive sorrow, and proceeded on, and could not relax till I found myself at Qarnath-Tha-alib where I lifted my head towards the sky to see a cloud shading me unexpectedly. I looked up and saw Gabriel in it. He called me saying, 'Allah has heard your people's saying to you, and what they have replied back to you, Allah has sent the Angel of the Mountains to you so that you may order him to do whatever you wish to these people.' The Angel of the Mountains called and greeted me, and then said, "O Muhammad! Order what you wish. If you like, I will let Al-Akh-Shabain (i.e. two mountains) fall on them." The Prophet said, "No but I hope that Allah will let them beget children who will worship Allah Alone, and will worship None besides Him."
