(65) باب بَيَانِ أَنَّ الْإِسْلَامَ بَدَأَ غَرِيبًا وَسَيَعُودُ غَرِيبًا وَأَنَّهُ يَأْرِزُ بَيْنَ الْمَسْجِدَيْنِ
It is narrated on the authority of Abu Huraira that the Messenger of Allah (ﷺ) said:
Islam initiated as something strange, and it would revert to its (old position) of being strange. so good tidings for the stranger.
