It is the name Muhammad, however, which gains the greatest awe and reverence in Islamic piety. Because it is believed to contain a very considerable blessing (barakah), many children are given the Prophet’s name or a similar derivative of it. Ja`far as-Sadiq, the sixth of the great Shi’ite Imams, is recorded as saying that everyone who bears the name of Muhammad shall, by that virtue alone, be entitled to enter Paradise. In the same way there is a tradition in Morocco that states that if in any house or tent there is a man with the name Muhammad, angels will always be present to protect the home and its inmates unless a black dog or band of musicians drives them away. In many poems it is said that the very mention of the Prophet’s name will bring blessings on the reciter but some poets and mystics have cautioned against its familiar use, saying that very few are qualified even to pronounce his pure and holy name. One said in a poem that even though he might wash his mouth a thousand times with musk and rose water it would still be an absolute impudence to mention his name. One of the commonest names of the Prophet, especially in the folk songs of the Muslim masses, is al-Mustafa, “the Chosen One”. Also in common use is the name al-Mujtaba, “the Elected One”, both names having become proper names for Muslim children. During religious ceremonies and festivals numerous praises are sung to the honor of the Prophet and invariably his personal name and the other titles given to him are an essential part of the devotion. The deep reverence he obtains throughout the Muslim world may not be immediately apparent to a non-Muslim observer but it is essential to appreciate it if Muslims are to be sincerely understood.
