Ibn Abbas was informed that so-and-so, a certain wife of the Prophet ﷺ, had died. He fell down prostrating himself. He was questioned: Why do you prostrate yourself this moment? He said: The Messenger of Allah ﷺ said: When you see a portent (an accident), prostrate yourselves. And which portent (accident) can be greater than the death of a wife of the Prophet ﷺ.  

أبو داود:١١٩٧ – حَدَّثَنَا مُحَمَّدُ بْنُ عُثْمَانَ بْنِ أَبِي صَفْوَانَ الثَّقَفِيُّ حَدَّثَنَا يَحْيَى بْنُ كَثِيرٍ حَدَّثَنَا سَلْمُ بْنُ جَعْفَرٍ عَنِ الْحَكَمِ بْنِ أَبَانَ عَنْ عِكْرِمَةَ قَالَ

قِيلَ لاِبْنِ عَبَّاسٍ مَاتَتْ فُلاَنَةُ بَعْضُ أَزْوَاجِ النَّبِيِّ ﷺ فَخَرَّ سَاجِدًا فَقِيلَ لَهُ أَتَسْجُدُ هَذِهِ السَّاعَةَ فَقَالَ قَالَ رَسُولُ اللَّهِ ﷺ إِذَا رَأَيْتُمْ آيَةً فَاسْجُدُوا وَأَىُّ آيَةٍ أَعْظَمُ مِنْ ذَهَابِ أَزْوَاجِ النَّبِيِّ ﷺ

tirmidhi:3891 – ʿAbbās al-ʿAnbarī > Yaḥyá b. Kathīr al-ʿAnbarī Abū Ghassān

"After Salat As-Subh, it was said to Ibn 'Abbas that so-and-so - one of the wives of the Prophet ﷺ - has died, so he prostrated. So it was said to him: 'Do you prostrate at this hour?' So he said: 'Has not the Messenger of Allah ﷺ [already] said: 'If you see a sign then prostrate?' Then which sign is grater than the passing of (one of) the wives of the Prophet ﷺ?'"  

Abū ʿĪsá said that this Ḥadīth is Ḥasan-Gharīb and we do not know of any other Ḥadīth except through this particular context.
