LessonsSifat al-Huruf — Seventeen Letter Characteristics and Their ApplicationQuiz

Lin denotes softness. Specifically, it occurs in an unvowelled و or ي preceded by a fathah. The sound passes smoothly through the letter, but this does not mean the consonant should automatically be prolonged as an ordinary madd letter.

In خَوْف, the still و follows a fathah on خ.
In بَيْت, the still ي follows a fathah on ب.

By contrast, قُولُوا has a madd waw after dammah and قِيلَ has a madd ya after kasrah. Their configuration differs from this definition of lin. The detailed rules for lengthening on a pause belong to later discussions.
