I am developing an instrument of Islamic religious behavior based on the hadith of Gabriel which divides Islam into 3 dimensions: Islam, Iman and Ihsan.
In your opinion, what are the indicators in Islam, Iman and Ihsan that I can include. Thank you
As far as behaviour is concerned, you may take into account the five pillars of Islam (shurut al-Islam) for Islam, for Iman that would be the pillars of belief (shurut al-Iman), and for ihsan you may take the overall of both pillars and look into the objectives of Shariah based on the analysis of darruriyyat, hajiyyat and tahsiniyyat. That would determine the Ihsan.
You may even develop the framework based on objectives of Shariah for what you have books available in plenti such as Shatibi's, Ghazali's books on maqasid.
