Sahih al-Bukhari Book 10, Hadith 100
Once a man was driving two Nadihas (camels used for agricultural purposes) and night had fallen. He
found Mu`adh praying so he made his camel kneel and joined Mu`adh in the prayer. The latter recited
Surat 'Al-Baqara" or Surat "An-Nisa", (so) the man left the prayer and went away. When he came to
know that Mu`adh had criticized him, he went to the Prophet, and complained against Mu`adh. The
Prophet said thrice, "O Mu`adh ! Are you putting the people to trial?" It would have been better if you
had recited "Sabbih Isma Rabbika-l-A`la (87)", Wash-shamsi wa duhaha (91)", or "Wal-laili idha
yaghsha (92)", for the old, the weak and the needy pray behind you." Jabir said that Mu`adh recited
Sura Al-Baqara in the `Isha' prayer.
A man came and said, "O Allah's Messenger (ﷺ)! I keep away from the morning prayer because so-and-so (Imam) prolongs it too much." Allah's Messenger (ﷺ) became furious and I had never seen him more furious than he was on that day. The Prophet (ﷺ) said, "O people! Some of you make others dislike the prayer, so whoever becomes an Imam he should shorten the prayer, as behind him are the weak, the old and the needy.''
The Prophet (ﷺ) used to pray a short prayer (in congregation) but used to offer it in a perfect manner.
