3. One should proceed to the Musjid calmly. One should not run to the Musjid.

عن أبي هريرة قال : سمعت رسول الله صلى الله عليه وسلم يقول : إذا أقيمت الصلاة فلا تأتوها تسعون وأتوها تمشون عليكم السكينة فما أدركتم فصلوا وما فاتكم فأتموا (صحيح البخاري رقم 908)

Hazrat Abu Hurairah (radhiyallahu ‘anhu) reports that I heard Rasulullah (sallallahu ‘alaihi wasallam) say, “When the iqaamat is called out for salaah, then do not proceed towards the salaah whilst you are running, rather come walking with ease and tranquility. Whatever portion of the salaah you perform with the imaam, then perform it; and whatever you missed out, then complete it (i.e. after the imaam completes the salaah).”
