Jabir reported: The Messenger of Allah (ﷺ) was ill and we said prayer behind him and he was sitting. And Abu Bakr (RA) was making audible to the people his takbir. As he paid his attention towards us he saw us standing and (directed us to sit down) with a gesture. So we sat down and said our prayer with his prayer in a sitting posture. After uttering salutation he said: You were at this time about to do an act like that of the Persians and the Romans. They stand before their kings while they sit, so don't do that; follow your Imams. If they say prayer standing, you should also do so, and if they say prayer sitting, you should also say prayer sitting.
Jabir said: The Messenger of Allah (ﷺ) led the prayer and Abu Bakr (RA) was behind him. When the Messenger of Allah (ﷺ) recited the takbir, Abu Bakr (RA) also recited (it) in order to make it audible to us. And the rest of the hadith is like one transmitted by Laith.
´It was narrated that Jabir said:` "The Messenger of Allah (ﷺ) was ill, and we prayed behind him while he was sitting, and Abu Bakr repeated his takbirs so that the people could hear them. He turned to us and saw us standing, so he gestured to us to sit down. So we prayed behind him sitting. When he said the salam he said: 'Just now you were doing what the Persians and Romans do for their kings when they are sitting. Do not do that. Follow your Imams: If they pray standing then pray standing, and if they pray sitting then pray sitting.'"
Hafiz Muhammad Ameen
1201. Commentary:
➊ It is permissible for the imam, when necessary, to look at the followers (muqtadis) with the corner of his eye. (For details, see Hadith: 1196)
➋ Should the followers (muqtadis) pray sitting or standing behind an imam who is leading the prayer while sitting? For its details, see Hadith: 833.
➌ This incident is not from the time of the Prophet’s (sallallahu alayhi wa sallam) final illness, because it is explicitly mentioned regarding this incident that Abu Bakr (radi Allahu anhu) and all the followers were standing. (The separate issue of whether the imam was the Prophet (sallallahu alayhi wa sallam) or Abu Bakr (radi Allahu anhu) — for this, see the introduction to the Book of Imamah.) This incident is from an earlier illness.

´It was narrated that Jabir said:` “The Messenger of Allah (ﷺ) fell ill, and we prayed behind him while he was sitting down, and Abu Bakr was saying the Takbir so that the people could hear them. He turned to us and saw us standing, so he gestured to us to sit down. When he had said the Salam, he said: ‘You were about to do the action of the Persians and Romans, who remain standing while their kings are seated. Do not do that. Follow the lead of your Imam; if he prays standing, then pray standing, and if he prays sitting down, then pray sitting down.’”

Benefits and Issues: ➊ The people of Persia and Rome were non-Muslims. The Iranians were fire-worshippers. And the Romans were Christians, who adhered to a distorted form of Christianity. The Prophet sallallahu alayhi wa sallam forbade imitation of non-Muslims.
➋ If a respected elder, leader, scholar, or spiritual guide is seated, then standing before him out of respect and refraining from sitting is not the way of Muslims; therefore, one should avoid this.
➌ Performing prayer standing behind a seated imam is, in some respects, different from standing out of respect for non-Muslims. Courtiers stand facing the king, and he too sits facing them with attention. Whereas the imam and all the followers (muqtadis) are all facing the Ka‘bah for the worship of Allah. The followers do not stand in front of the imam, but rather behind him. Moreover, courtiers remain standing continuously, whereas the followers do not remain standing during bowing (ruku‘), prostration (sujud), sitting (jalsah), and the testimony (tashahhud). It is probably for this reason that the Prophet sallallahu alayhi wa sallam, during the last days of his blessed life, did not forbid the followers from standing in prayer when he led them while seated. And Allah knows best.
