রিয়াদুস সালেহীন ৪২৬

The Prophet (ﷺ) used to perform two Rak'ah short prayer between the Adhan (call to prayer) and the Iqamah of the dawn (Fajr) prayers.In the narration of Muslim, 'Aishah (May Allah be pleased with her) said: When the Messenger of Allah (ﷺ) used to hear the Adhan (of Fajr prayer) he would perform two supererogatory Rak'ah prayer and would make them short.

The Messenger of Allah (ﷺ) used to perform his optional night prayers at night, two Rak'ah followed by two Rak'ah, and at the end he would conclude with an odd Rak'ah (Witr). Then he would perform two Rak'ah prayer before the dawn (Fajr) prayer after hearing the Adhan, and he would make them so brief as if he could hear the Iqamah being called..

I went to inform the Messenger of Allah (ﷺ) about the time of the dawn (Fajr) prayer, and 'Aishah (May Allah be pleased with her) kept me busy and began to ask me about something till the day grew bright. Then I got up and informed the Messenger of Allah (ﷺ) of the time of Salat. I informed him again but he did not came out immediately to lead As- Salat. When he came out, he led As-Salat. I said to him: 'Aishah (May Allah be pleased with her) kept me busy and thus diverted my attention by asking about something and the morning grew bright. You also came out late. Upon that the Messenger of Allah (ﷺ) said, "I was engaged in performing two Rak'ah of Fajr prayer." Bilal (May Allah be pleased with him)said: "O Messenger of Allah! You delayed As-Salat so long as the morning grew bright." He (ﷺ) replied, "Even if the morning had become brighter than it had, I would have performed two Rak'ah of prayer in an excellent manner.".
