Not hastening unduly to join a prayer in progress

If the prayer starts and a person is still on his way to the mosque, he should not hasten unduly; he should walk with calmness and dignity, as indicated in the hadeeth of Abu Hurayrah (may Allaah be pleased with him): “The Prophet (peace and blessings of Allaah be upon him) said: ‘If the prayer starts, do not approach it running; approach it walking with calmness and dignity. Whatever you catch up with, pray, and whatever you miss, complete it [afterwards].’” (Reported by al-Bukhaari, Fath, 2/390).
