According to tradition, Muhammad played a role in the restoration of the Kaaba, after parts of it had been destroyed by one of Mecca's frequent flash floods.
When the reconstruction was almost done, disagreements arose among the clan leaders as to who would have the honor of lifting the sacred Black Stone into place.
The disagreements increased to the point where the clans were about to take up arm against each other, when one of the elders suggested they take the advice of the next person who entered the gates of the Haram.
This happened to be Muhammad.
He spread out his cloak, put the stone in the middle and had members of the four major clans raise it to its destined position.
The cloak became an important symbol for later poets and writers because of this event and what happened later as described in the Hadith of the Cloak.

What is commonly referred to as the "interest rate" in the media is generally the rate offered on overnight deposits by the Central Bank or other authority, annualized.
The total interest on a loan or investment depends on the timescale the interest is calculated on, because interest paid may be compounded.
In retail finance, the annual percentage rate and effective annual rate concepts have been introduced to help consumers easily compare different products with different payment structures.
In business and investment finance, the effective interest rate is often derived from the yield, a composite measure which takes into account all payments of interest and capital from the investment.
The notion of annual effective discount rate, often called simply the "discount rate", is also used in finance, as an alternative measure to the effective annual rate which is more useful or standard in some contexts.
A positive annual effective discount rate is always a lower number than the interest rate it represents.

Allmusic wrote that the album was uneven, but that "...what was first-rate was also highly memorable, and what wasn't also wasn't bad."

Saudi Arabia, and specifically the Hejaz, as the cradle of Islam, has many of the most significant historic Muslim sites, including the two holiest sites of Mecca and Medina.
One of the King's titles is Custodian of the Two Holy Mosques, the two mosques being Masjid al-Haram in Mecca, which contains Islam's most sacred place, the Kaaba, and Al-Masjid al-Nabawi in Medina which contains Muhammad's tomb.
However, Saudi Wahhabism is hostile to any reverence given to historical or religious places of significance for fear that it may give rise to 'shirk' (that is, idolatry).
As a consequence, under Saudi rule, the Hejaz cities have suffered from considerable destruction of their physical heritage and, for example, it has been estimated that about 95% of Mecca's historic buildings, most over a thousand years old, have been demolished.
These include the mosque originally built by Muhammad's daughter Fatima, and other mosques founded by Abu Bakr (Muhammad's father-in-law and the first Caliph), Umar (the second Caliph), Ali (Muhammad's son-in-law and the fourth Caliph), and Salman al-Farsi (another of Muhammad's companions).
Other historic buildings that have been destroyed include the house of Khadijah, the wife of the Prophet, the house of Abu Bakr, now the site of the local Hilton hotel; the house of Ali-Oraid, the grandson of the Prophet, and the Mosque of abu-Qubais, now the location of the King's palace in Mecca.
Critics have described this as "Saudi vandalism" and claim that over the last 50 years, 300 historic sites linked to Muhammad, his family or companions have been lost.
It has been reported that there now are fewer than 20 structures remaining in Mecca that date back to the time of Muhammad.
