It was narrated that 'Aishah said:"The sun was eclipsed during the time of the Messenger of Allah (ﷺ), and the Prophet (ﷺ) commanded a caller to call out that prayer was about to begin in congregation. So they gathered and formed rows, and he led them in prayer, bowing four times in two rak'ahs and prostrating four times."
أَخْبَرَنِي عَمْرُو بْنُ عُثْمَانَ بْنِ سَعِيدٍ، قَالَ حَدَّثَنَا الْوَلِيدُ، عَنِ الأَوْزَاعِيِّ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، قَالَتْ خَسَفَتِ الشَّمْسُ عَلَى عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم فَأَمَرَ النَّبِيُّ صلى الله عليه وسلم مُنَادِيًا يُنَادِي أَنَّ الصَّلاَةَ جَامِعَةً فَاجْتَمَعُوا وَاصْطَفُّوا فَصَلَّى بِهِمْ أَرْبَعَ رَكَعَاتٍ فِي رَكْعَتَيْنِ وَأَرْبَعَ سَجَدَاتٍ .
