Is the sitting for rest recommended or obligatory?

It appears the questioner is from Sudan; because he says, according to what you mentioned regarding the corner, but he also says in his message: It is mentioned in Sahih al-Bukhari regarding the sitting for rest. We ask you to clarify: is it a sunnah or recommended? And if one of us prays with the congregation, and all of these people and their imam do not perform it, while we do perform it, what is the ruling on our prayer and their prayer?
Answer: The sitting for rest is recommended (mustahabb) and not obligatory. Your prayer is valid, and their prayer is valid, and praise be to Allah. The Messenger of Allah (peace and blessings be upon him) performed it, as narrated by Malik ibn al-Huwayrith in Sahih al-Bukhari meaning: a light sitting, which is called the sitting for rest. And Abu Humayd al-Sa'idi al-Ansari narrated it likewise. So it is recommended and a sunnah. And some of the scholars said: It is recommended for the elderly and the sick, because it is difficult for them to stand up quickly. And the apparent meaning of the hadith is that it is recommended for everyone; because the narrator mentioned it as part of the description of the Prophet's (peace and blessings be upon him) prayer, so that indicates that it is recommended. And if the imam does not sit for it, and the ma'mum and most of the ma'mum do not sit for it, there is no harm in you sitting for it and then standing up. It does not harm you and it does not harm them. Your prayer is valid, all of you. And the best is to perform it in emulation of the Prophet (peace and blessings be upon him). And whoever does not perform it, there is no blame on him. And praise be to Allah. Yes.
