Arabic

حَدَّثَنَا آدَمُ، حَدَّثَنَا شُعْبَةُ، عَنْ حُمَيْدٍ الطَّوِيلِ، سَمِعْتُ أَنَسَ بْنَ مَالِكٍ ـ رضى الله عنه ـ قَالَ كَانَتِ الأَنْصَارُ يَوْمَ الْخَنْدَقِ تَقُولُ نَحْنُ الَّذِينَ بَايَعُوا مُحَمَّدَا عَلَى الْجِهَادِ مَا حَيِينَا أَبَدَا فَأَجَابَهُمُ اللَّهُمَّ لاَ عَيْشَ إِلاَّ عَيْشُ الآخِرَهْ فَأَكْرِمِ الأَنْصَارَ وَالْمُهَاجِرَهْ
