1. When leaving home for the Masjid or for any other place, recite this Dua: (Tirmidhi, Abu Dawood, Ibne Maajah)

Trans:  I emerge with the name of Allah. I have placed my trust in Allah. The strength to abstain from sins and to carry out righteous deeds, is only from Allah (Shami , Vol.1  pg. 85)

2. Proceed with dignity. Do not run. (This pertains to going to the Masjid only).  (Ibne Majah)
