Types of mutawatir
Hadiths can be
mutawatir in both actual
text and
meaning:
Mutawatir in wording
A
hadith whose words are narrated by such a large number as is required for a
mutawatir, in a manner that all the narrators are unanimous in reporting it with the same words without any substantial discrepancy.
For example: "[Muhammad said:] Whoever intentionally attributes a lie against me, should prepare his seat in the Fire." This is a
mutawatir hadith in its wordings because it has a minimum of seventy-four narrators. In other words, seventy-four companions of Muhammad have reported this
hadith at different occasions, all with the same words. The number of those who received this
hadith from the Companions is many times greater, because each of the seventy four Companions has conveyed it to a number of his students. Thus the total number of narrators of this
hadith has been increasing in each successive generation and has never been less than seventy-four. All these narrators who now are hundreds in number, report it in the same words without even a minor change. This
hadith is therefore mutawatir in its wording, because it cannot be imagined reasonably that such a large number of people have colluded to coin a fallacious sentence in order to attribute it to Muhammad.
Mutwatir in meaning
A
hadith which is not reported by
multiple narrators using the same words. The words of the narrators are different. Sometimes even the reported events are not the same.
But all the narrators are unanimous in reporting a basic concept, which is common in all reports. This common concept is also ranked as a mutawatir concept.
For example: It is reported by such a large number of narrators that Muhammad enjoined Muslims to perform two
ra'kat in
Fajr, four ra'kat in
Dhuhr,
Asr and
Esha and three ra'kat in the Maghrib prayer, yet the narrations of all the reporters who reported the number of ra'kat are not in the same words. Their words are different and even the events reported by them are different. But the common feature of all the reports is the same: the exact number of ra'kat. The
hadith is thus said to be
mutawatir in meaning.
