Not Prolonging the Congregational Prayer
Abu Hurayrah (radi Allahu anhu) reported that the Messenger of Allah (sal Allahu alaihi wa sallam) said, “When one of you leads the salat, he should not prolong it because the congregation includes those who are feeble, ill or old”.
[Sahih al-Bukhari and Muslim]
According to this Hadith, the Imam – one who leads the congregational prayer, is enjoined to shorten the prayer in consideration of those who pray behind him.
Shortening of prayer here means that the Surah of the Qur’an recited by him in the prayer should not be very long. This does not mean, however, that the postures of Salat, such as standing, bowing, prostration and sitting should not be done properly, as it is taken to mean by Muslims in general.
Although it is a Sunnah about which the Noble Prophet (sal Allahu alaihi wa sallam) is reported to have said, “Pray as you see me praying.” Thus, it is essential to perform Salat properly.
And Allah Knows Best!
