7 has always been my favorite number. It's very lucky for me.

Yes, I know. It is also an interesting number (7 deadly sins, etc) and can be known to be a lucky number

various Hindus wrote 7 more or less in one stroke as a curve that looks like an uppercase J but vertically inverted.

More so ,The western Ghubar Arabs' main contribution was to make the longer line diagonal rather than straight, though they showed some tendencies to making the character

That is some great information. Is there anything else you know?

 As is the case with the European glyph, the Cham and Khmer glyph for 7 also evolved to look like their glyph for 1, though in a different way

You have educated me very well on the number 7. Thank you.

You are welcome!Modern Arab forms influenced the European form, a two-stroke character consisting of a horizontal upper line joined at its right to a line going down to the bottom corner, 7 also depicts some religious importance
