Sahih al-Bukhari Book 10, Hadith 48
The Prophet (ﷺ) said, "The people who get tremendous reward for the prayer are those who are farthest
away (from the mosque) and then those who are next farthest and so on. Similarly one who waits to
pray with the Imam has greater reward than one who prays and goes to bed. "
I heard Um Ad-Darda' saying, "Abu Ad-Darda' entered the house in an angry mood. I said to him. 'What makes you angry?' He replied, 'By Allah! I do not find the followers of Muhammad doing those good things (which they used to do before) except the offering of congregational prayer." (This happened in the last days of Abu Ad-Darda' during the rule of `Uthman) .
Allah's Messenger (ﷺ) said, "While a man was going on a way, he saw a thorny branch and removed it from the way and Allah became pleased by his action and forgave him for that." Then the Prophet (ﷺ) said, "Five are martyrs: One who dies of plague, one who dies of an Abdominal disease, one who dies of drowning, one who is buried alive (and) dies and one who is killed in Allah's cause." (The Prophet (ﷺ) further said, "If the people knew the reward for pronouncing the Adhan and for standing in the first row (in the congregational prayer) and found no other way to get it except by drawing lots they would do so, and if they knew the reward of offering the Zuhr prayer early (in its stated time), they would race for it and if they knew the reward for `Isha' and Fajr prayers in congregation, they would attend them even if they were to crawl.
