“Certainly you have in the Messenger of Allah an excellent exemple for him who hopes in Allah and the latter day and remembers Allah much.” (Qur’an 33:21)
Malik ibn al-Huwayrith reported: The Prophet, (saw), said, “Pray as you have seen me praying. When the time of prayer arrives, let one of you announce the call to prayer for you and then let the older of you leader the prayer.” Source: (Sahih Bukhari 5662)
One of the most contentions issues among Muslims more often than not has to do with the way the Blessed Messenger (saw) did his prayers. This video below is well worth the listen. It is done by a brother who follows the Hanafi school of jurisprudence with in the Sunni denomination of Islam.
What he is explaining is that it is impossible to find a ‘Sahih’ hadith for every single act that is done in the prayer. Which is something that I have come to a conclusion about a long time ago. He than argues this is why for some Muslims in the Sunni denomination they decide to follow a school of jurisprudence.
The truth of the matter is that the prayer was established by the Blessed Messenger (saw). It is a mass transmitted sunnah. The hadith are written records for those who need to furnish proofs for things that were found to be objectionable. Things that stood out as different needed to have a proof or evidence, more so than something people picked up as mass practice from those who preceded them and from those who preceded them.
