Overall meaning:
Al-Barāʾ ibn ʿĀzib describes the Prophet’s prayer, peace and blessings be upon him, noting that its parts were balanced and harmonious. His standing for Qur’an recitation and his sitting for the tashahhud matched his bowing, his rising from bowing, and his prostration; he would not, for instance, lengthen the standing yet shorten the bowing, or prolong the prostration and then abbreviate the standing or the sitting. Instead, every pillar was kept in due proportion to the others.
This does not mean that the standing and the tashahhud were exactly equal in length to the bowing and the prostration. Rather, it means that he did not make one pillar excessively light while burdening another. It is in fact known that the standing and the final sitting were longer than the other movements, as al-Bukhārī’s additional wording in the hadith indicates.
Points derived from the hadith:
1- It is preferable that bowing and the standing after it, as well as prostration and the sitting between the two prostrations, be of roughly equal duration, so the worshipper does not greatly prolong one over the other.
2- The standing for recitation and the final sitting for the tashahhud should be longer than the other pillars.
3- The prayer as a whole should be proportionate; thus, the length of the recitation should correspond, for example, to the length of the bowing and the prostrations.
4- The obligation of tranquillity (tumaʾnīnah) in standing upright after bowing and in the sitting between the two prostrations is firmly established, contrary to those who rush through their prayer and fail to straighten their backs in these two postures.
5- Some have claimed that rising from bowing is a “minor pillar” because repeated glorifications are not prescribed in it as they are in bowing and prostration. This is a faulty analogy that contradicts the textual evidence, for the remembrance legislated in the standing after bowing is actually longer than that prescribed in the bowing itself, as Muslim records in a report from three Companions.
Benefit:
Because the Prophet’s customary practice was to lengthen the standing for recitation and the sitting for the tashahhud more than the other parts of the prayer, the commentators have differed over how this proportionality among the acts—including the standing—should be understood. Al-Nawawī judged it to be a circumstantial description rather than a constant rule.
