[Machine] I said to Mujahid, "Is the mark of prostration on the face of a person?" He replied, "No, but one of them may have a mark between his eyes like the knee of a goat, which means he may have a mark due to evil, but it is actually a mark of humility." Ja'ir narrated to us from Tha'labah, from Ja'far ibn Abi Mu'ghira, from Sa'id ibn Jubayr, who said, "It is the dew of purification and the soil of the earth."  

قُلْتُ لِمُجَاهِدٍ {سِيمَاهُمْ فِي وُجُوهِهِمْ مِنْ أَثَرِ السُّجُودِ} [الفتح 29] أَهُوَ أَثَرُ السُّجُودِ فِي وَجْهِ الْإِنْسَانِ؟ فَقَالَ لَا إِنَّ أَحَدَهُمْ يَكُونُ بَيْنَ عَيْنَيْهِ مِثْلُ رُكْبَةِ الْعَنْزِ وَهُوَ كَمَا شَاءَ اللهُ يَعْنِي مِنَ الشَّرِّ لَكِنَّهُ الْخُشُوعُ قَالَ وَحَدَّثَنَا جَرِيرٌ عَنْ ثَعْلَبَةَ عَنْ جَعْفَرِ بْنِ أَبِي مُغِيرَةَ عَنْ سَعِيدِ بْنِ جُبَيْرٍ قَالَ نَدَى الطُّهُورِ وَثَرَى الْأَرْضِ
