It was narrated from ‘Abdullah that the Messenger of Allah ﷺ said:
“Islam began as something strange and will go back to being strange, so glad tidings to the strangers.” It was said: “Who are the strangers?’ He said: “Strangers who have left their families and tribes.”

حَدَّثَنَا سُفْيَانُ بْنُ وَكِيعٍ، حَدَّثَنَا حَفْصُ بْنُ غِيَاثٍ، عَنِ الأَعْمَشِ، عَنْ أَبِي إِسْحَاقَ، عَنْ أَبِي الأَحْوَصِ، عَنْ عَبْدِ اللَّهِ، قَالَ قَالَ رَسُولُ اللَّهِ ـ ﷺ ـ " إِنَّ الإِسْلاَمَ بَدَأَ غَرِيبًا وَسَيَعُودُ غَرِيبًا فَطُوبَى لِلْغُرَبَاءِ " . قَالَ قِيلَ وَمَنِ الْغُرَبَاءُ قَالَ النُّزَّاعُ مِنَ الْقَبَائِلِ .
