عَنْ عَلِيٍّ وَمُعَاذِ بْنِ جَبَلٍ رَضِيَ اللَّهُ عَنْهُمَا قَالَا: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِذَا أَتَى أَحَدُكُمْ الصَّلَاةَ وَالْإِمَامُ عَلَى حَالٍ فَلْيَصْنَعْ كَمَا يَصْنَعُ الْإِمَامُ» . رَوَاهُ التِّرْمِذِيُّ وَقَالَ: هَذَا حَدِيثٌ غَرِيبٌ

Anas reported God’s Messenger as saying, “If anyone prays to God for forty days in congregation being present in time for the first takbira, two immunities will be recorded for him, one from hell and one from hypocrisy,” Tirmidhi transmitted it.
