´It was narrated that Anas bin Malik said:` “The Messenger of Allah (ﷺ) used to make his prayer brief but perfect.”
Brief Explanation
1؎: It would be shortened in such a way that the surahs would not be recited very long, and it would be complete in the sense that the prostration (sajdah), standing (qiyam), and sitting (qa'dah) would be performed properly. At the very least, one would remain in prostration and bowing (ruku') for the duration of five or three tasbihs, and similarly, after rising from bowing, one would stand up straight and say «سمع الله لمن حمده ربنا ولك الحمد حمدا كثيرا طيبا مباركا فيه».

From this, the meaning of lightening the prayer becomes clear: that the acts (arkaan) of the prayer should be performed with complete humility (khushu‘) and tranquility (itmi’nan), but the amount of recitation (tilawah) and glorifications (tasbihat) should not be so excessive that the followers (muqtadis) become distressed.

Shaykh Abdul Sattar al-Hammad
Hadith Commentary:
Imam Bukhari rahimahullah intends to establish that brevity in prayer does not contradict its perfection, because from the Messenger of Allah sallallahu alayhi wa sallam, both brevity and perfection in prayer are proven. Therefore, it is recommended that one should not prolong the prayer to such an extent that it becomes burdensome for the followers (muqtadis), nor should it be so brief that it causes deficiency in the pillars (arkan) and proper composure (ta'dil).
This is clarified in a hadith: Hazrat Anas radi Allahu anhu states that he never prayed behind any imam who performed the prayer more briefly and more perfectly than the Messenger of Allah sallallahu alayhi wa sallam.

Hadith Commentary: Benefits and Issues:
According to Qadi Iyad rahimahullah,
(correct)
If a word was not read by the transmitter of the manuscript of Muslim rahimahullah,
then he wrote in its place "an kaza wa kaza" ("from so-and-so"), "anzur" ("see"),
meaning:
Investigate this word,
and then the meaning and intent of "an kaza wa kaza" was explained: "that they will come over the people."
If the narrations of other Companions radi Allahu anhum are taken into consideration,
then the purpose is that the people will be on a mound,
and your ummah will be on a mound higher than them.
