Hadith #1

أَبِی ره قَالَ حَدَّثَنِی سَعْدُ بْنُ عَبْدِ اللَّهِ عَنْ مُحَمَّدِ بْنِ الْحُسَیْنِ بْنِ أَبِی الْخَطَّابِ عَنْ وَهْبِ بْنِ حَفْصٍ عَنْ أَبِی بَصِیرٍ قَالَ سَمِعْتُ أَبَا عَبْدِ اللَّهِ ع یَقُولُ إِنَّ رَسُولَ اللَّهِ ص قَالَ: یَا أَیُّهَا النَّاسُ أَقِیمُوا صُفُوفَکُمْ وَ امْسَحُوا بِمَنَاکِبِکُمْ لِئَلَّا یَکُونَ فِیکُمْ خَلَلٌ وَ لَا تُخَالِفُوا فَیُخَالِفَ اللَّهُ بَیْنَ قُلُوبِکُمْ وَ إِنِّی أَرَاکُمْ مِنْ خَلْفِی.

1. My father (rah) said: it was narrated to me by Sa’d b. Abdillah from Muhammad b. al-Hussain b. Abi al-Khattab from Wahab b. Hafs from Abi Basir who said I heard Aba Abdillah (a.s.) says that The Messenger of Allah (s.a.w.s.) who said: “O people! Make your rows proper. Your shoulders should touch that of the people standing beside you. There should be no gap between two persons. Don’t remain aloof from a row so that Allah does not create difference between you people. Know that I am seeing the people who create differences among you.”
