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
Allah hath fulfilled the vision for His messenger in very truth. Ye shall indeed enter the Inviolable Place of Worship, if Allah will, secure, (having your hair) shaven and cut, not fearing. But He knoweth that which ye know not, and hath given you a near victory beforehand.
