taqiyyah
2ـ ابْنُ أَبِي عُمَيْرٍ عَنْ هِشَامِ بْنِ سَالِمٍ عَنْ أَبِي عُمَرَ الأعْجَمِيِّ قَالَ قَالَ لِي أَبُو عَبْدِ الله (عَلَيهِ السَّلام) يَا أَبَا عُمَرَ إِنَّ تِسْعَةَ أَعْشَارِ الدِّينِ فِي التَّقِيَّةِ وَلا دِينَ لِمَنْ لا تَقِيَّةَ لَهُ وَالتَّقِيَّةُ فِي كُلِّ شَيْ‏ءٍ إِلا فِي النَّبِيذِ وَالْمَسْحِ عَلَى الْخُفَّيْنِ.
2. Ibn abu ‘Umayr has narrated from Hisham ibn Salim from abu ‘Umar al-‘ A’jami who has said the following: “Once Abu ‘Abdillah (a.s.) said to me, ‘O abu ‘Umar, nine tenths of religion is in al- Taqiyyah (cautious measures). One who does not observe al- Taqiyyah has no religion. Al-Taqiyyah must be observed in all matters except wine and wiping (a part of Wuzu) over the socks.’”
