(3) باب مَا عُرِضَ عَلَى النَّبِيِّ صلى الله عليه وسلم فِي صَلاَةِ الْكُسُوفِ مِنْ أَمْرِ الْجَنَّةِ وَالنَّارِ
Asma' said:
I came to 'A'isha when the people were standing (in prayer) and she was also praying. I said: What is this excitement of the people for? And the rest of the hadith was narrated like one, (narrated above). 'Urwa said: Do not say Kasafat-ush-Shamsu, but say Khasafat-ush-Shamsu.
