"I heard Allah's Messenger saying: 'Perform Fajr at AI-Isfar, for indeed its reward is greater.'"
Jami` at-Tirmidhi Book 2, Hadith 6
← Previous Hadith "Allah's Messenger would pray Subh (at such time that) the women would leave (after the prayer)" - AI-AnsarI (one of the narrators) said - the women would pass by wrapped in their Mirts and they would not be recognizable due to the darkness." And Qutaibah said: "covered." (instead of "wrapped.")
