Narrated Ibn 'Abbas (RA): Allah's Messenger ( صلی اللہ علیہ وسلم ) said that, "Dawn is of two types; the dawn in which eating is forbidden (for the fasting person) and prayer is permitted and the dawn in which prayer is forbidden i.e. the morning prayer and eating is permitted." [Reported by Ibn Khuzaimah and al-Hakim who (both) graded it Sahih] . al-Hakim reported something similar to the above Hadith from Jabir and added to the type of dawn in which eating is forbidden: "it is spread widely in the horizon," and to the other type: "it has the shape of wolf's tail."

Narrated Ibn Mas'ud (RA): Allah's Messenger ( صلی اللہ علیہ وسلم ) said: "One of the best deeds is to offer Salat (prayer) in its early time." [Reported by at-Tirmidhi and al-Hakim who (both) graded it Sahih] . Its basic meaning is in the Sahihain of al-Bukhari and Muslim.

Narrated Abu Mahdhurah (RA): The Prophet ( صلی اللہ علیہ وسلم ) said: "The earliest time of prayer is what pleases Allah, the midtime is for the mercy of Allah and the latest time is what Allah pardons." [Reported by ad-Daraqutni with a very weak Sanad (chain)] . at-Tirmidhi has reported something similar, narrated by Ibn 'Umar, without mentioning the midtime. [It is Da'if (weak) too] .

Narrated Ibn 'Umar (RA): Allah's Messenger ( صلی اللہ علیہ وسلم ) said: "There is no Salat (i.e. voluntary prayer) after the break of dawn except Sajdatain (Sunnah of Fajr)." [Reported by al-Khamsah except an-Nasa'i] . In another narration: 'Abdur-Razzaq also narrated: "There is no Salat (voluntary prayer) after the break of dawn ecept the two (Sunnah) Rak'a of Fajr." A narration of ad-Daraqutni narrated by Amr bin al-'Aas is similar to the one above.

Narrated Umm Salamah (RA): Allah's Messenger ( صلی اللہ علیہ وسلم ) came to my house after offering 'Asr prayer and offered two Rak'a, then I asked him about that and he replied, "I was kept busy (and failed to pray) the two (Sunnah) Rak'a after Zuhr prayer, so I offered them now." I asked him, "Should we offer them if we miss them?" He ( صلی اللہ علیہ وسلم ) replied, "No." [Reported by Ahmad] . The narration of Abu Dawud from 'Aishah (RA) has the same meaning.
