I was interested in the Miracle of Fatima and the reported Hidden Words of Fatima as having a Muslim origin. So I found that the name of the city “Fatima” was original named after Fatima the daughter of Prophet Muhammad:
"The name of the town and parish is a rendition of the Arabic given name Fátima (فاطمة Fāṭimah). (Fatimah is the namesake of Fatimah bint Muhammad, a daughter of the prophet of Islam Muhammad.)"
“Fátima was said to be the name of a Moorish princess kidnapped by a knight, Gonçalo Hermigues, and his companions. Hermigues took her to a small village in the Serra de Aire hills, in the recently created Kingdom of Portugal. According to the Western Catholic narrative, Fatima fell in love with her kidnapper and decided to convert to Christianity in order to marry him. She was baptized and given a Christian name, Oureana.[3]
Arab sources, however, claim that Fátima was forced into Christianity,[4] as were most Reconquista captives. There is no documentary evidence to support either scenario of such a conversion.”
Regarding the “Hidden Words” British orientalist Edward Granville Browne wrote:
“After the Prophet’s death Fátima was affected in spirit to a degree which none but God knew. Jebrá’íl was sent down daily to comfort her, and 'Alí wrote what the angel said, and this is the Book of Fátima which is now with the Imám Mahdí.” On consulting Rieu’s Catalogue of the Persian MSS. in the British Museum, I found mention (vol. ii, p. 829 b.) of a work entitled ~~~ composed by Mullá Muhsin-i-Feyz of Káshán, and described as consisting of “one hundred sayings of Imáms and Súfís in Arabic, with Persian commentary.” I seized the first opportunity of examining this work, but a search of about two hours through its pages revealed nothing resembling the passages in the text before us. Finally I wrote to Acre, asking, amongst other questions, what might be the true nature of the work here alluded to. The following answer (which is authoritative) was returned:- [Translation] “Fifth Question. Concerning the mention of the matters in the Hidden Book of Fátima (upon her be the peace of God). The answer is this, that the sect of Persia, that is the Shi’ites, who regard themselves as pure, and the [rest of the] world (we take refuge with God!] as unclean, believe that after His Highness the Seal of the Prophets [Muhammad] Her Highness Fátima (upon her be the blessings of God) was occupied night and day in weeping, wailing, and lamenting over the fate of her illustrious father. Therefore was Jebrá’íl commanded by the Lord Most Glorious to commune, converse, and associate with Her Highness Fátima; and [footnote goes onto page 124] he used to speak words causing consolation and quietude of heart. These words were collected and named ‘The Book of Fátima’ (~~~). And they [i.e. the Shi’ites] believe that this Book is with His Highness the Ká’im [i.e. the Imám Mahdí] and shall appear in the days of his appearance.”
