When there are already 1000 questions are the islam.StackExchange, I found it interesting to ask the question 1001 about 1001 names of Allah:
There is a Du'a narrated from Imam Ali-ibn-Hussain from prophet Muhammad (PBUH) called Joushan Kabir Dua (this links contain Du'a in Arabic, English and Persian) that is 100 parts, each containing 10 beautiful names of Allah. Also part 55 contains 11 names, so the total names of Allah in this Du'a will be 1001. I found calling Allah by 1001 names not only an very good way to ask him my needs - specially in Qadr nights, but also a excellent way to think and learn better about my Lord.
So my question is: How many names are provided for Allah (Asma-ul-Husna) in Hadith or Sunnah? Is there any name of Allah missing from this great Du'a, or is there any other source with more names of Allah? If not, maybe we can consider these 1001 names are all the names Muslims know about Allah.
