*Wants Reward Like That of Hajj And ‘Umrah.*.... *“In full, in full, in full.”*
Al-Tirmidhi narrated that Anas ibn Maalik (may Allaah be pleased with him) said: The Messenger of Allaah (peace and blessings of Allaah be upon him) said: “Whoever prays Fajr in congregation then sits remembering Allaah until the sun rises, then prays two rak’ahs, will have a reward like that of Hajj and ‘Umrah.” He said: The Messenger of Allaah (peace and blessings of Allaah be upon him) said: “In full, in full, in full.”
This hadeeth was classed as hasan by al-Albaani in Saheeh al-Tirmidhi.
This points to the virtue of sitting in the mosque after Fajr prayer, and the virtue of praying two rak’ahs when the sun has risen fully.
In general, if a person stays in the mosque to remember Allaah (dhikr) and worship Him, or waiting for the prayer, all of these are good deeds and acts of worship that bring one closer to Allaah. Al-Bukhaari (445) and Muslim (649) narrated from Abu Hurayrah that the Messenger of Allaah (peace and blessings of Allaah be upon him) said: “The angels send blessings upon one of you so long as he is in his prayer-place where he offered his prayer, so long as he does not break his wudoo’; they say: ‘O Allaah forgive him, O Allaah have mercy on him.’”
