Imaam Bukhari (rahmatullahi alayhi) has mentioned a hadith [more or less] that whomsoever goes in the path of Allah (fee-sabeelillah) and dust gathers on their feet, then Allah will forbid the fire of Hell on them. This hadith was put under the Chapter of Juma'a and Imaam Bukhari has applied it to all Muslims going for Juma Prayers:
أدركني أبو عبس، وأنا أذهب إلى الجمعة، فقال: سمعت النبي صلى الله عليه وسلم يقول: (من اغبرت قدماه في سبيل الله حرمه الله على النار
"How much time & sacrifice should Muslims put-in (or sacrifice) for the pleasure of Allah so that we are closer to the practice (manhaj) of the sahaba?"
