﴿ 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 ﴾

“Indeed, God has shown the truth in His Apostle’s true vision: most certainly shall you enter the Inviolable House of Worship, if God so wills, in full security, with your heads shaved or your hair cut short, without any fear: for He has [always] known that which you yourselves could not know. And He has ordained [for you], besides this, a victory soon to come.”
