When the sun eclipsed in the lifetime of Allah's Apostle and an announcement was made that the prayer was to be held in congregation. The Prophet performed two bowing in one Raka. Then he stood up and performed two bowing in one Raka. Then he sat down and finished the prayer;
and by then the (eclipse) had cleared 'Aisha said, "I had never performed such a long prostration."
حَدَّثَنَا أَبُو نُعَيْمٍ، قَالَ حَدَّثَنَا شَيْبَانُ، عَنْ يَحْيَى، عَنْ أَبِي سَلَمَةَ، عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو، أَنَّهُ قَالَ لَمَّا كَسَفَتِ الشَّمْسُ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ نُودِيَ إِنَّ الصَّلاَةَ جَامِعَةٌ فَرَكَعَ النَّبِيُّ ﷺ رَكْعَتَيْنِ فِي سَجْدَةٍ ثُمَّ قَامَ فَرَكَعَ رَكْعَتَيْنِ فِي سَجْدَةٍ، ثُمَّ جَلَسَ، ثُمَّ جُلِّيَ عَنِ الشَّمْسِ. قَالَ وَقَالَتْ عَائِشَةُ ـ رضى الله عنها ـ مَا سَجَدْتُ سُجُودًا قَطُّ كَانَ أَطْوَلَ مِنْهَا.
