The Indian census of 1901 tells us how the pure monotheism of Mohammed has been debased by contact with worship at human shrines: "We have seen in the case of Hinduism that the belief in one supreme God, in whom are vested all ultimate powers, is not incompatible with the belief in Supernatural Beings who exercise considerable influence over worldly affairs, and whose influence may be obtained or averted by certain ceremonies. Similarly, in the case of Islam, while the masses have, on the whole, a clearer idea of the unity and omnipotence of God than the ordinary Hindu has, they also have a firm belief in the value of offerings at certain holy places for obtaining temporal blessings. Thus the shrine of Saiyad Salar, at Bahraich, is resorted to, both by Hindus and Mussulmans, if a wife is childless, or if family quarrels cannot be composed. Diseases may be cured by a visit to the shrine of Shaik Saddo, at Amroha in Moradabad; while for help in legal difficulties Shah Mina's dargah at Lucknow is renowned. Each of these has its appropriate offering,--a long embroidered flag for the first, a cock for the second, and a piece of cloth for the third. Other celebrated shrines are those of Bahauddin Madar Shah at Nakkanpur in the Cawnpore district, and of Ala-uddin Sabir at Piran Kaliar in Saharanpur." The same writer, in his report concerning Bengal, says: "The unreformed Mohammedans of the lower and uneducated classes are deeply infected with Hindu superstitions, and their knowledge of the faith they profess seldom extends beyond the three cardinal doctrines of the Unity of God, the mission of Mohammed, and the truth of the Quran; and they have a very faint idea of the differences between their religion and that of the Hindus. Sometimes they believe that they are descended from Abel (Habil), while the Hindus owe their origin to Cain (Kabil). Kabil, they say, killed Habil and dug a grave for him with a crow's beak."
