question #2 Sahih Muslim 906a, Book 10, Hadith 15 : What is the significance of the Prophet’s prolonged prayer during the solar eclipse?

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.
