Sahih Muslim 2106
صحيح مسلم#2106SahihAsma' bint Abu Bakr said: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
