عَنْ أَبِي أُمَامَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «عَلَيْكُمْ بِقِيَامِ اللَّيْلِ فَإِنَّهُ دَأْبُ الصَّالِحِينَ قَبْلَكُمْ وَهُوَ قُرْبَةٌ لَكُمْ إِلَى رَبِّكُمْ وَمَكْفَرَةٌ لِلسَّيِّئَاتِ وَمَنْهَاةٌ عَنِ الْإِثْمِ» . رَوَاهُ التِّرْمِذِيّ

Abu Sa'id al-Khudri reported God’s Messenger as saying, “There are three on whom God looks with pleasure

a man when he gets up at night and prays, a company when they draw up in rows in prayer, and a company when they draw up in ranks to fight the enemy." [Baghawi] transmitted it in Sharh as-sunna.
