Qalqalah can be of two types:

a) Strong echoing (قَلْقَلَةُ كُبْرَى) — happens if there is a qalqalah letter with tashdeed at the end of a word and we stop at this word.

b) Medium echoing (قَلْقَلَةُ صُغْرَى) happens when we stop on a word which end with sukoon. Sukoon can be there because of a stop or it could be originally in that word.

c) Subtle echoing: (قَلْقَلَةُ صُغْرَى) can occur in the middle of a word or in the middle of a sentence.

تَبَّتۡ یَدَاۤ أَبِی لَهَبࣲ وَتَبَّ
