Narrated Abu Mas`ud Al-Ansari: Once a man said to Allah's Apostle "O Allah's Apostle! I may not attend the (compulsory congregational) prayer because so and so (the Imam) prolongs the prayer when he leads us for it. The narrator added: "I never saw the Prophet more furious in giving advice than he was on that day. The Prophet said, "O people! Some of you make others dislike good deeds (the prayers). So whoever leads the people in prayer should shorten it because among them there are the sick the weak and the needy (having some jobs to do).

Narrated Abu Mas`ud: A man came and said, "O Allah's Apostle! By Allah, I keep away from the morning prayer only because So and so prolongs the prayer when he leads us in it." The narrator said, "I never saw Allah's Apostle more furious in giving advice than he was at that time. He then said, "Some of you make people dislike good deeds (the prayer). So whoever among you leads the people in prayer should shorten it because among them are the weak, the old and the needy."

Narrated Abu Huraira: Allah's Apostle said, "If anyone of you leads the people in the prayer, he should shorten it for amongst them are the weak, the sick and the old; and if anyone among your prays alone then he may prolong (the prayer) as much as he wishes. "

Narrated Abu Mas`ud: A man came and said, "O Allah's Apostle! I keep away from the morning prayer because so-and-so (Imam) prolongs it too much." Allah's Apostle became furious and I had never seen him more furious than he was on that day. The Prophet 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.''

Narrated Jabir bin `Abdullah Al-Ansari: 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.

Narrated Jabir bin `Abdullah: Mu`adh used to pray with the Prophet and then go and lead his people (tribe) in the prayer.

Narrated Al-Bara': I learnt, 'Glorify the Name of your Lord the Most High' (Surat al-A'la) No 87, before the Prophet came (to Medina) .

Narrated Jabir bin `Abdullah: Mu`adh bin Jabal used to pray with the Prophet and then go to lead his people in prayer. Once he led the people in prayer and recited Surat-al-Baqara. A man left (the row of the praying people) and offered (light) prayer (separately) and went away. When Mu`adh came to know about it, he said. "He (that man) is a hypocrite." Later that man heard what Mu`adh said about him, so he came to the Prophet and said, "O Allah's Apostle! We are people who work with our own hands and irrigate (our farms) with our camels. Last night Mu`adh led us in the (night) prayer and he recited Sura-al-Baqara, so I offered my prayer separately, and because of that, he accused me of being a hypocrite." The Prophet called Mu`adh and said thrice, "O Mu`adh! You are putting the people to trials? Recite 'Washshamsi wad-uhaha' (91) or'Sabbih isma Rabbi ka-l-A'la' (87) or the like."

Narrated Abu Mas`ud: A man came to the Prophet and said "I keep away from the morning prayer only because such and such person prolongs the prayer when he leads us in it. The narrator added: I had never seen Allah's Apostle more furious in giving advice than he was on that day. He said, "O people! There are some among you who make others dislike good deeds) cause the others to have aversion (to congregational prayers). Beware! Whoever among you leads the people in prayer should not prolong it, because among them there are the sick, the old, and the needy." (See Hadith No. 670, Vol 1)

Narrated Abu Mas`ud Al-Ansari: A man came to Allah's Apostle and said, "O Allah's Apostle! By Allah, I fail to attend the morning congregational prayer because so-and-so (i.e., Mu`adh bin Jabal) prolongs the prayer when he leads us for it." I had never seen the Prophet more furious in giving advice than he was on that day. He then said, "O people! some of you make others dislike (good deeds, i.e. prayers etc). So whoever among you leads the people in prayer, he should shorten it because among them there are the old, the weak and the busy (needy having some jobs to do). (See Hadith No. 90, Vol. 1)
