The Shaykh : Our scholars, may Allah be pleased with them,
The student: Amen.

The Shaykh : when they would write a hadith.
The student: Yes.

The Shaykh : It would most likely be a circle, like the circle that is used today at the end of verses, but a hollow, empty circle, not decorated as it is now in the mushafs.
The student : Yes, yes.

The Shaykh : The book would be copied by the copyist.
The student: Yes.

The Shaykh : According to the orderThe Shaykh : and it would end.

The student: Yes.

The Shaykh : The Shaykh : The one holding the original and the reader holding his copy.
The student: Yes.

The Shaykh : Every time the reading of a hadith was finished, a dot was placed in the middle of the circle.
The student: Yes.

The Shaykh : What does this mean? It is finished.
The student : It is finished.

The Shaykh : This hadith has been checked.
The student: Yes.

The Shaykh : You may find a copy of the book where the dots continue to a quarter of its text, or to three-quarters of it, and the rest has no dots. You must be aware that this remainder which has no dots has not been checked.
The student : It has not been checked.

The Shaykh : It means, be careful that it is not finished.
The student : It is not finished.

The Shaykh : So now, you have placed a hadith dot in your speech until I answer you.
The student: Hehehe.
