The Messenger of Allah ﷺ saw a person praying alone. He said: Is there any man who may do good with this (man) and pray along with him. (Using translation from Abū Dāʾūd 574)   

أَنَّ النَّبِيَّ ﷺ رَأَى رَجُلًا يُصَلِّي وَحْدَهُ فَقَالَ «أَلَا رَجُلٌ يَتَصَدَّقُ عَلَى هَذَا فَيُصَلِّي مَعَهُ»  

[Machine] A man entered the mosque after the Prophet ﷺ had prayed and said, "Is there not a man who will give charity to him so that he can pray with him?" Abdullah said, "He prays the afternoon prayer and the sunset prayer, but he intercedes."  

أَنَّ رَجُلًا دَخَلَ الْمَسْجِدَ وَقَدْ صَلَّى النَّبِيُّ ﷺ فَقَالَ «أَلَا رَجُلٌ يَتَصَدَّقُ عَلَى هَذَا فَيُصَلِّي مَعَهُ؟» قَالَ عَبْدُ اللَّهِ يُصَلِّي صَلَاةَ الْعَصْرِ وَيُصَلِّي الْمَغْرِبَ وَلَكِنْ يَشْفَعُ
