Mishkat al-Masabih 4 Prayer كتاب الصلاة 793

وَعَن سَمُرَةَ بْنِ جُنْدُبٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «احْضُرُوا الذِّكْرَ وَادْنُوا مِنَ الْإِمَامِ فَإِنَّ الرَّجُلَ لَا يَزَالُ يَتَبَاعَدُ حَتَّى يُؤَخَّرَ فِي الْجنَّة وَإِن دَخلهَا» . رَوَاهُ أَبُو دَاوُد

Samura b. Jundub reported God’s Messenger as saying, “Be present at the mention of God and go near the imam ; for if anyone always keeps far away the result will be that he will be put in a back place in paradise, supposing he enters it.” Abu Dawud transmitted it.
