According to Dr Zakir Naik, Allah is mentioned in Hindu scriptures:
"Allah" in Rigveda Book 2 Hymn I verse II Even in the Rigveda which is the most sacred scripture of the Hindus, one of the attributes given to God Almighty in Book no 2 Hymn no I verse II, is ‘Ila’ which if pronounced properly is the same as Allah.
Allo Upanishad: Amongst the various Upanishads one of the Upanishad is named as ‘Allo’ Upanishad in which God is referred to as "Allah" several times.
According to Bhavishya Purana in the Prati Sarag Parv III Khand 3 Adhay 3 Shloka 5 to 8. "A malecha (belonging to a foreign country and speaking a foreign language) spiritual teacher will appear with his companions. His name will be Mohammad. Raja (Bhoj) after giving this Maha Dev Arab (of angelic disposition) a bath in the Panchgavya and the Ganga water (i.e. purifying him of all sins) offered him the present of his sincere devotion and showing him all reverence said, "I make obeisance to thee. O ye! The pride of mankind, the dweller in Arabia, Ye have collected a great force to kill the Devil and you yourself have been protected from the malecha opponents."
The Prophecy clearly states:
The name of the Prophet as Mohammad.
He will belong to Arabia. The Sanskrit word Marusthal means a sandy track of land or a desert.
Special mention is made of the companions of the Prophet, i.e. the Sahabas. No other Prophet had as many companions as Prophet Muhammad (pbuh).
He is referred as the pride of mankind (Parbatis nath). The Glorious Qur’an reconfirms this
"And thou (standest) on an exalted standard of character" [Al-Qur'an 68:4]|
"Ye have indeed in the Messenger of Allah, a beautiful pattern (of conduct)". [Al-Qur'an 33:21]
He will kill the devil, i.e. abolish idol worship and all sorts of vices.
The Prophet will be given protection against his enemy.
Some people may argue that ‘Raja’ Bhoj mentioned in the prophecy lived in the 11th century C.E. 500 years after the advent of Prophet Muhammad (pbuh) and was the descendant in the 10th generation of Raja Shalivahan. These people fail to realise that there was not only one Raja of the name Bhoj. The Egyptian Monarchs were called as Pharaoh and the Roman Kings were known as Caesar, similarly the Indian Rajas were given the title of Bhoj. There were several Raja Bhoj who came before the one in 11th Century C.E.
The Prophet did not physically take a bath in the Panchgavya and the water of Ganges. Since the water of Ganges is considered holy, taking bath in the Ganges is an idiom, which means washing away sins or immunity from all sorts of sins. Here the prophecy implies that Prophet Muhammad (pbuh) was sinless, i.e. Maasoom.
The above gives evidence of Allah and Muhammad.
Question: Is it possible that Hinduism was founded by a Prophet of Allah but has been changed into polytheism?
