4ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ عَبْدِ الله بْنِ سِنَانٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ سَأَلْتُهُ عَنْ مَوْضِعِ جَبْهَةِ السَّاجِدِ يَكُونُ أَرْفَعَ مِنْ قِيَامَةٍ قَالَ لاَ وَلَكِنْ يَكُونُ مُسْتَوِياً. وَفِي حَدِيثٍ آخَرَ فِي السُّجُودِ عَلَى الأرْضِ الْمُرْتَفِعَةِ قَالَ قَالَ إِذَا كَانَ مَوْضِعُ جَبْهَتِكَ مُرْتَفِعاً عَنْ رِجْلَيْكَ قَدْرَ لَبِنَةٍ فَلاَ بَأْسَ.
4. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from ‘Abd Allah ibn Sinan who has said the following: “I once asked abu ‘Abd Allah (a.s.), about the place of Sujud (prostration) if it can be higher than the place where one stands. He (the Imam) said, ‘No, it must be level.’ In another Hadith about the place of Sujud (prostration) which is higher than the place on which one stands, it is said that if it is of the height of a brick it is not harmful.’”
