Ikrima reported,

Someone said to Ibn Abbas, "So-and-so has died," referring to one of the wives of the Prophet ﷺ. He fell down in prostration.He was asked, "Do you prostrate at this moment?"He replied, "The Messenger of Allah ﷺ said, 'When you see a sign, prostrate.' And what sign is greater than the passing of the wives of the Prophet ﷺ?"

عن عكرمة قال

قيل لابن عباس: ماتت فلانة- بعض أزواج النبي ﷺ- فخر ساجدا. فقيل له: أتسجد هذه الساعة؟ فقال: قال رسول الله ﷺ: إذا رأيتم آية فاسجدوا وأي آية أعظم من ذهاب أزواج النبي ﷺ.
