[1] Avicenna was born in Afsanah at 980, a village near Bukhara (now in present-day Uzbekistan).
Nasr refers to the book of Isharat as the last and greatest masterpiece of Avicenna.
[3] The word “Isharat” is a synonym for signs, remarks, indications and hints.
Sometimes Avicenna refers to Isharah by words like A follow-up, a closing comment and wish.
The most famous ones are Nasir al-Din al-Tusi Tusi (Sharh al-isharat) and Imam Fakhr Razi’s and an explanation and description by Allame Hassan Hasanzadeh Amoli.
