Qur'ān 48:27 · Al-Fath (الفتح)

لَّقَدْ صَدَقَ ٱللَّهُ رَسُولَهُ ٱلرُّءْيَا بِٱلْحَقِّ ۖ لَتَدْخُلُنَّ ٱلْمَسْجِدَ ٱلْحَرَامَ إِن شَآءَ ٱللَّهُ ءَامِنِينَ مُحَلِّقِينَ رُءُوسَكُمْ وَمُقَصِّرِينَ لَا تَخَافُونَ ۖ فَعَلِمَ مَا لَمْ تَعْلَمُوا۟ فَجَعَلَ مِن دُونِ ذَٰلِكَ فَتْحًۭا قَرِيبًا

Certainly has Allah showed to His Messenger the vision in truth. You will surely enter al-Masjid al-Haram, if Allah wills, in safety, with your heads shaved and [hair] shortened, not fearing [anyone]. He knew what you did not know and has arranged before that a conquest near [at hand].
