Hadith No. 60
From Ayesha –Radi Allaahu anha– who said:

From Ayesha from the Prophet -sallAllaahu alayhi wa sallam- who said:
‘Two Rakat for Sunnah of Fajr prayer are better than the Dunyaa and everything that is in it.’ [Muslim, Tirmidhi & Nisa’ee]
From Ayesha –Radi Allaahu anha– who said from the Prophet -sallAllaahu alayhi wa sallam- that he said about the two Rakat when the Fajr prayer time comes in:
