1. No I agree but then Sikhism too like Buddhism, is spin off from Hinduism...all of their Gurus were Hindus except the last one who created Khalsa....ironically that too to save Hindus from atrocities of Muslim rulers and stop forced conversion to Islam..So will you not call Sikhism as a religion?.... further Islam, Christianity and Jews are spin off of same Judaism of ancient Israelite, who worshipped God of Abraham(and hence called Abrahamic religions)... are they not separate religions then?
2. Does Islam instruct to worship a specific God? Isn't it a religion then? you are contradicting yourself here.
3. Disagree. Bakhtiyar Khalji was born and raised in
Garmsir,
Helmand, in present-day southern Afghanistan. He was member of the
Khalaj tribe, a tribe of
Turkic origin that after migration from Turkistan had settled in
Afghanistan for over 200 years.
