Arabic hadith text
وَعَنْ وَابِصَةَ بْنِ مَعْبَدٍ قَالَ: رَأَى رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ رَجُلًا يُصَلِّي خَلْفَ الصَّفِّ وَحْدَهُ فَأَمَرَهُ أَنْ يُعِيدَ الصَّلَاةَ. رَوَاهُ أَحْمَدُ وَالتِّرْمِذِيُّ وَأَبُو دَاوُدَ وَقَالَ التِّرْمِذِيُّ هَذَا حَدِيثٌ حَسَنٌ
Translation
Wabisa b. Ma'bad said that God’s Messenger saw a man praying alone behind the row and ordered him to repeat the prayer. Ahmad Tirmidhi and Abu Dawud transmitted it, and Tirmidhi said this is a hasan tradition.
