١٦ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ حَمَّادٍ عَنْ حَرِيزٍ عَنْ زُرَارَةَ قَالَ قُلْتُ لأَبِي جَعْفَرٍ (عَلَيْهِ الْسَّلام) رَجُلٌ خَرَجَ مِنْ سَفِينَةٍ عُرْيَاناً أَوْ سُلِبَ ثِيَابُهُ وَلَمْ يَجِدْ شَيْئاً يُصَلِّي فِيهِ فَقَالَ يُصَلِّي إِيمَاءً فَإِنْ كَانَتِ امْرَأَةً جَعَلَتْ يَدَهَا عَلَى فَرْجِهَا وَإِنْ كَانَ رَجُلاً وَضَعَ يَدَهُ عَلَى سَوْأَتِهِ ثُمَّ يَجْلِسَانِ فَيُومِئَانِ إِيمَاءً وَلاَ يَسْجُدَانِ وَلاَ يَرْكَعَانِ فَيَبْدُو مَا خَلْفَهُمَا تَكُونُ صَلاَتُهُمَا إِيمَاءً بِرُءُوسِهِمَا قَالَ وَإِنْ كَانَا فِي مَاءٍ أَوْ بَحْرٍ لُجِّيٍّ لَمْ يَسْجُدَا عَلَيْهِ وَمَوْضُوعٌ عَنْهُمَا التَّوَجُّهُ فِيهِ يُومِئَانِ فِي ذَلِكَ إِيمَاءً رَفْعُهُمَا تَوَجُّهٌ وَوَضْعُهُمَا. 
16. Ali ibn Ibrahim has narrated from his father from Hammad from Hariz from Zurarah who has said the following: “I once asked abu Ja‘far , about a man who sails in a boat while naked or his clothes are looted and does not find anything to perform Salah (prayer) with. He (the Imam) said, ‘He performs Salah (prayer) by making gestures and a woman in such condition places her hand over her vagina, and if a man, he places his hand over his private part. They sit and make gestures and do not perform Sajdah (prostration) or Ruku‘ (bowing down on one’s knees) so their back is exposed. Their Salah (prayer) is by gestures by their heads.’ He (the Imam) said, ‘If they are in water or sea with waves they do not perform Sajdah (prostration) and they are exempt from facing (the direction of al- Qiblah (al-Ka‘bah)). They make gestures: their rising and lowering is gestures.’”
