Silsilat al-Ahadith al-Sahihah

Sayyiduna Abu Hurairah (may Allah be pleased with him) says: The Messenger of Allah (peace and blessings be upon him) sent out an army, and they returned quickly after obtaining a great deal of spoils of war. A man said: O Messenger of Allah! We saw this army that returned very quickly and brought back a lot of spoils. The Prophet (peace and blessings be upon him) said: “Shall I not inform you of someone who returns sooner than this army and obtains more spoils than them? (I mean) the person who performs ablution well at home, then walks towards the mosque, performs the Fajr prayer, and after that prays the Duha prayer and then returns (from the mosque); he has returned sooner and obtained more spoils.”

Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Whoever offers the Fajr prayer in congregation, then sits and remembers Allah until the sun rises, then prays two rak'ahs, he will receive the reward of a complete, complete, and complete Hajj and Umrah."
