That is really no Sikhi. When the gurus said - I am not a Hindu and I am not a Muslim, they did not mean to start a new religion but to get out of religious differences. Sikhs made themselves into a religion. That is not what the gurus intended.
I was told the naive/ silly story of how Sikhs were made to protect Hindus from Muslims. But upon further reading we can see that Guru Gobind Singh fought the Hindu hill people.
and it seems that Sikhism is some sort of reformation act; I think the complications of rituals and the caste system of Hinduism became too overwhelming for the people of Punjab (although one could argue Sikhism is not easy to abide by e.g. covering head, bowing down to a book in place of praying to idols, langar etiquette,etc.)
I don't understand your answers- if the Gurus didn't intend to create a new religion and wanted to sort out differences, why are they different today? I guess Sikhism has its own virtues and its three pillars; similar to Islam. But do Sikhs not talk much about Muhammad if they wanted to draw upon Islam? Guru Nanak's wife was originally Muslim and Bhai Mardana was also Muslim but I think Bhai Mardana converted to Sikhi
ਮਹਾਦੀਨ ਕੇਤੇ ਪ੝ਰਿਥੀ ਮਾਂਝ ਹੂਝ ॥ ਸਮੈ ਆਪਨੀ ਆਪਨੀ ਅੰਤ ਮੂਝ ॥੨੭॥,
Many Muhammads had been on the earth. They were born and then died in their own times.
ਮਹਾਦੀਨ ਤਬ ਪ੝ਰਭ ਉਪਰਾਜਾ ॥ ਅਰਬ ਦੇਸ ਕੋ ਕੀਨੋ ਰਾਜਾ ॥੨੬॥
Then I created Muhammed, who was made the master of Arabia.
What you said Aupmanyav, sounds more like Shirdi Sai Baba; though like with Sikhism he's been elevated to divinity in Hinduism but not mentioned much in Islam.
I see no mention of Shirdi Sai Baba or the Sikh Gurus in countries like Jordan, Egypt, Syria or Yemen.
