3-212 Muhammad ibn Ibrahim ibn Ahmad ibn Yunus al-Laysee narrated that Abu Abdullah Muhammad ibn al-Faraj al-Sharooty quoted Abu Abdullah Muhammad ibn Yazid ibn al-Molheb, on the authority of Abu Sufyan, on the authority of Oaf, on the authority of Maymun, on the authority of Al-Bara ibn Azib,

“When God’s Prophet (MGB) ordered that a ditch be dug, a big boulder appeared across the ditch which could not bebroken with a pickaxe. When the Prophet of God (MGB) came and saw it, he (MGB) took off his shirt, picked up the pickaxe, said God’s name and struck the boulder. One third of it broke up. The Prophet (MGB) said, ‘In the Name of God’ and hit it once. One third of it broke up into pieces. Then the Prophet (MGB) said, ‘God is Great. I have been given the keys to Syria. It is as if I can now see its red palaces’ and hit it a second time. Then the Prophet (MGB) said, ‘God is Great. It is as if I have been given the keys to Persia. I swear by God that I can see the White Palaces in Al-Madaen’ and hit it for the third time. Then the third part of the boulder broke into pieces. Then the Prophet (MGB) said, ‘God is Great. I have been given the keys to Yemen. It is as if I can see San’a - the capital from here.’”
