The Book of Prayer
Narrated Ubai bin Ka'b (RA):
"He [the Prophet (ﷺ)] prayed (the Eclipse prayer) and bowed five times and prostrated twice (in the first Rak'ah), and in the second Rak'a he also did the same." [Abu Dawud]
وَلِأَبِي دَاوُدَ: عَنْ أُبَيِّ بْنِ كَعْبٍ: { صَلَّى, فَرَكَعَ خَمْسَ رَكَعَاتٍ وَسَجَدَ سَجْدَتَيْنِ, وَفَعَلَ فِي اَلثَّانِيَةِ مِثْلَ ذَلِكَ } 1‏ .‏
