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.  

أَنَّهَا قَالَتْ فَزِعَ النَّبِيُّ ﷺ يَوْمًا قَالَتْ تَعْنِي يَوْمَ كَسَفَتِ الشَّمْسُ فَأَخَذَ دِرْعًا حَتَّى أُدْرِكَ بِرِدَائِهِ فَقَامَ لِلنَّاسِ قِيَامًا طَوِيلاً لَوْ أَنَّ إِنْسَانًا أَتَى لَمْ يَشْعُرْ أَنَّ النَّبِيَّ ﷺ رَكَعَ مَا حَدَّثَ أَنَّهُ رَكَعَ مِنْ طُولِ الْقِيَامِ
