1123. A person should offer his prayer whilst observing succession, meaning that he should perform the components of prayer, such as rukÙ, sujÙd, and tashahhud, in consecutive continuity. He should not interlude between them to a degree that would break the form of the prayer. He should similarly maintain the succession in the recitations of prayer, in a manner that is normal. If he interludes between them to such a degree that it would not be said that he is praying, his prayer will be invalid.

1124. If a person deliberately interludes between the letters or words of prayer to such a degree that their form, or their composition breaks, his prayer will be deemed invalid, unless he is an exculpatory ignorant, and the interlude is not to a degree that would break the form of prayer and it is not in takbÐrat al-iÎrÁm.
If a person inadvertently interludes between the letters or words of prayer, and the interlude is not to the degree that would break the form of prayer, and it is not in takbÐrat al-iÎrÁm, he should repeat the letters or words in their usual manner, so long as he has not entered the next pillar. If something after that has been recited, it is necessary to repeat it. However, if one has not entered the next pillar, his prayer will be valid. If there is no pillar after it, such as the last tashahhud, he should repeat the letters or words and that which is after them if he realizes it prior to the salÁm. However, if he realizes after the salÁm, his prayer will be valid.
If a person interludes between the letters or words of salÁm to a degree that would eliminate its succession, he should act according to the instructions elaborated in articles 1115 and 1116, concerning one forgetting to recite the salÁm.

1125. Elongating rukÙ or sujÙd, or reciting a lengthy sÙrah does not break the form of prayer.
