As Almighty Allah says in Quran, that even if one brings all the oceans and turn it into ink and all the trees in this world made the pen, still, what Allah has created can not be described. Keeping this in view our efforts can be termed as a drop in the ocean, yet in a positive direction.

This book is open to all those who want to improve it and if any correction is required, we will be thankful to those, who will inform us about this, after all this is a human effort.
