Fourth, this is done only by someone intent on multiplying letters and words, even though doing so may diminish or alter the meaning. If he reflected on what he was saying, he would realize that each transmitted wording achieves the intended purpose, although some achieve it more fully. For when he says, “much wrongdoing,” whatever is much is also great in meaning, and whatever is great is also much in meaning.

In short, if one formula of remembrance agrees with the other in its essential meaning, they are like two Quranic readings with the same meaning. If their meanings differ, they are like two Quranic readings with differing meanings. In either case, combining them on a single occasion is not prescribed. As for combining two forms of the prayer in times of fear, the testimony recited while seated in prayer, the call to commence prayer, or similar practices, this is prohibited by the consensus of the Muslims.
