عَنْ أَبِي أُمَامَةَ رَضِيَ اللَّهُ عَنْهُ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ رَأَى رَجُلًا يُصَلِّي فَقَالَ: ((أَلَا رَجُلٌ يَتَصَدَّقُ عَلَى هَٰذَا فَيُصَلِّي مَعَهُ))، فَقَامَ رَجُلٌ فَصَلَّى مَعَهُ، فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((هَٰذَانِ جَمَاعَةٌ))
Sayyiduna Abu Umamah (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) saw a man praying alone and said: "Is there not anyone who will give charity to him and pray with him?" So a man stood up and prayed with him. Then the Messenger of Allah (peace and blessings be upon him) said: "These two men are a congregation."
