Ayesha's Khandani Chicken Biryani

I have always been searching for a recipe for an authentic Muslim Biryani and have made several attempts at cooking it. The "Shilpa's Chicken Biryani" that I have published was the closest I could get to it. Although  "Shilpa's Chicken Biryani"  is great tasting and easy to make, its not really the authentic one.
On Ramzan festival this year, I made "Sheer Khurma" with some guidance from an old friend and it turned out great, however I did not have enough time to actually ask her how to make the authentic Muslim biryani.
On the same day, another friend of mine, who now lives in Sharjah, sent me this recipe. And it was a surprise... Wonder how she read my mind across so many miles...

This is the authentic Muslim biryani which her family is cooking from generations...
My joy knew no bounds when I saw her message. I was thrilled, and today I managed to make it!!
Yes this is the answer to my years of trying to make the Muslim Biryani, "Success" or should I say "Roaring Success..."
Thank you Ayesha for the recipe.... You were like an answer to our prayers.....
So Foodies... here it is...."The authentic Muslim Biryani" ... and with due credit to my friend I am naming it "Ayesha's Khandani Chicken Biryani"!
You could replace the chicken with mutton if you wish.
