عَنْ سَهْلِ بْنِ سَعْدٍ قَالَ كُنَّا مَعَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ بِالْخَنْدَقِ وَهُمْ يَحْفِرُونَ وَنَحْنُ نَنْقُلُ التُّرَابَ عَلَى أَكْتَافِنَا فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ اللَّهُمَّ لَا عَيْشَ إِلَّا عَيْشُ الْآخِرَةِ فَاغْفِرْ لِلْمُهَاجِرِينَ وَالْأَنْصَارِ
It is narrated from Sayyiduna Sahl bin Sa’d (may Allah be pleased with him) that on the occasion of the Trench, we were with the Messenger of Allah (peace and blessings be upon him). The noble Companions were digging the trench and we were carrying the soil on our shoulders and transferring it. Seeing this scene, the Messenger of Allah (peace and blessings be upon him) said: O Allah! There is no life except the life of the Hereafter, so forgive the Muhajireen and the Ansar.
