The Holy Quran, Surat Al-Fat-h - الفتح

لَقَدْ صَدَقَ اللَّهُ رَسُولَهُ الرُّؤْيَا بِالْحَقِّ لَتَدْخُلُنَّ الْمَسْجِدَ الْحَرَامَ إِن شَاء اللَّهُ آمِنِينَ مُحَلِّقِينَ رُؤُوسَكُمْ وَمُقَصِّرِينَ لَا تَخَافُونَ فَعَلِمَ مَا لَمْ تَعْلَمُوا فَجَعَلَ مِن دُونِ ذَلِكَ فَتْحاً قَرِيباً

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.

مُّحَمَّدٌ رَّسُولُ اللَّهِ وَالَّذِينَ مَعَهُ أَشِدَّاء عَلَى الْكُفَّارِ رُحَمَاء بَيْنَهُمْ تَرَاهُمْ رُكَّعاً سُجَّداً يَبْتَغُونَ فَضْلاً مِّنَ اللَّهِ وَرِضْوَاناً سِيمَاهُمْ فِي وُجُوهِهِم مِّنْ أَثَرِ السُّجُودِ ذَلِكَ مَثَلُهُمْ فِي التَّوْرَاةِ وَمَثَلُهُمْ فِي الْإِنجِيلِ كَزَرْعٍ أَخْرَجَ شَطْأَهُ فَآزَرَهُ فَاسْتَغْلَظَ فَاسْتَوَى عَلَى سُوقِهِ يُعْجِبُ الزُّرَّاعَ لِيَغِيظَ بِهِمُ الْكُفَّارَ وَعَدَ اللَّهُ الَّذِينَ آمَنُوا وَعَمِلُوا الصَّالِحَاتِ مِنْهُم مَّغْفِرَةً وَأَجْراً عَظِيماً

Muhammad is the messenger of Allah. And those with him are hard against the disbelievers and merciful among themselves. Thou (O Muhammad) seest them bowing and falling prostrate (in worship), seeking bounty from Allah and (His) acceptance. The mark of them is on their foreheads from the traces of prostration. Such is their likeness in the Torah and their likeness in the Gospel like as sown corn that sendeth forth its shoot and strengtheneth it and riseth firm upon its stalk, delighting the sowers that He may enrage the disbelievers with (the sight of) them. Allah hath promised, unto such of them as believe and do good works, forgiveness and immense reward.
