Is the sitting of rest recommended?

Question:
What about the light sitting before standing up?

Answer:
As for the sitting, this is a recommended practice (sunnah), and it is called the sitting of rest. It is not obligatory. Whoever does it has done well, and whoever does not, there is no blame on him. It is established that the Prophet (peace and blessings be upon him) used to do it in his prayer (peace and blessings be upon him). Some scholars have held that it is not recommended, and that the Prophet’s (peace and blessings be upon him) doing of it is attributed to the fact that he had grown old and it had become heavy for him.
The correct view is that it is recommended in all cases. This is the correct view; because it is established from the Prophet (peace and blessings be upon him) and from a group of the Companions (may Allah be pleased with them) . This indicates its recommendation after the first and third rak'ahs in the four-rak'ah prayer, after the first rak'ah in all prayers, and after the third rak'ah in the four-rak'ah prayer. It is a light sitting, like the sitting between the two prostrations.
Likewise, the recommended practice is to place the right hand over the left hand, the wrist, and the forearm when standing. One places the right hand over the left hand, over the wrist and the forearm. The hand is on part of the palm, on the palm, and part of it on the wrist, and part of the fingers on the forearm, as the Prophet (peace and blessings be upon him) did, as this is established in the hadith of Wa'il ibn Hujr (may Allah be pleased with him) Yes.
