Sahih Muslim , Book 10, Hadith 15 (In-Book) ⓘ

Asma' bint Abu Bakr said: The Apostle of Allah 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 had observed ruku', as it has been narrated about ruku' in connection with long qiyam.

حَدَّثَنَا يَحْيَى بْنُ حَبِيبٍ الْحَارِثِيُّ، حَدَّثَنَا خَالِدُ بْنُ الْحَارِثِ، حَدَّثَنَا ابْنُ جُرَيْجٍ، حَدَّثَنِي مَنْصُورُ بْنُ عَبْدِ الرَّحْمَنِ، عَنْ أُمِّهِ، صَفِيَّةَ بِنْتِ شَيْبَةَ عَنْ أَسْمَاءَ بِنْتِ أَبِي بَكْرٍ، أَنَّهَا قَالَتْ فَزِعَ النَّبِيُّ صلى الله عليه وسلم يَوْمًا - قَالَتْ تَعْنِي يَوْمَ كَسَفَتِ الشَّمْسُ - فَأَخَذَ دِرْعًا حَتَّى أُدْرِكَ بِرِدَائِهِ فَقَامَ لِلنَّاسِ قِيَامًا طَوِيلاً لَوْ أَنَّ إِنْسَانًا أَتَى لَمْ يَشْعُرْ أَنَّ النَّبِيَّ صلى الله عليه وسلم رَكَعَ مَا حَدَّثَ أَنَّهُ رَكَعَ مِنْ طُولِ الْقِيَامِ ‏.‏
