Question

This is a question relating to a small meem present at the end of some of the small surahs at the end of the Qur'an (for example:  surah Al-Ikhlas  and  Al-Nasr )  The small meem you have explained some time before (Oct. 20th) means a stop but why would it be at the end of these few surahs? and not at the end of others?

Answer

Assalaam alaikum wa rahmatu Allahi wa barakatuhu.

There are two different small meems used in the diatricts/annotations in the copies of the Qur’an, one of these two meems has a tail , as seen in the examples above on the last word in each of the two aayaat, indicate that the  saakinah of the tanween is followed by the letter , and therefore the iqlaab rule of the  saakinah occurs, and the  changes into a meem .  You may wonder where this letter  is that is causing the iqlaab-it is in the basmalah 
( ) that starts the next surah.  We therefore would only employ this rule of iqlaab when joining the end of the surah with the basmalah and the first part of the next surah, all in one breath.  This meem with the long tail indicates a  saakinah rule, and does not refer to stopping.

 

The second meem used in annotations of the Qur’an has a very short tail: .  This meem is used for a compulsory stop mark. 

Insha’ Allah the two different uses of the meem in Qur'anic diatricts/annotations are clearer now.
