If someone interrupts his reading or recitation of Qur’an for a valid reason, such as sneezing, or returning the greeting of salaam, or answering a question, and the like, and he intends to complete his reading or recitation once the excuse is no longer there, then the first isti‘aadhah is sufficient, and he is not instructed to repeat it, unless the interruption goes on for a long time, in which case he should repeat it.
