" It was for a long duration that he (the Holy Prophet) observed qiyam and he would then observe ruku'. (The narrator also added) I (Asma') looked at a woman who was older than I, and at another who was weaker than I.
Sahih Muslim Book 10, Hadith 16
← Previous Hadith The Apostle of Allah (ﷺ) was one day (i. e. on the day when the sun eclipsed) so perturbed that he (in haste) took hold of the outer garment (of a female member of his family) and it was later on that his (own) cloak was sent to him. He stood in prayer along with people for such a long time that if a man came he did not realise that the Messenger of Allah (ﷺ) had observed ruku', as it has been narrated about ruku' in connection with long qiyam.

Sahih Muslim Book 10, Hadith 15 Next Hadith → The sun eclipsed during the lifetime of the Messenger of Allah (ﷺ) ; so he felt perturbed and he, by mistake, took hold of the outer garment of a woman till he was given his own cloak. After this I satisfied my need and then came and entered the mosque. I saw the Messenger of Allah (ﷺ) standing in prayer. I stood along with him. He prolonged his qiyam till I wished to sit down. Then I cast a glance towards an old woman. So I said: She is older than I. I, therefore, kept standing. He (the Holy Prophet) then observed ruku', and prolonged his ruku'. He then raised his head. He then prolonged his qiyam to such an extent that if a person happened to come he would have thought that he had not observed the ruku'.
