Hadith 1732
۞
2. Ali has narrated from his father and Muhammad ibn Yahya from Ahmad ibn Muhammad all from Ibn Abi ‘Umayr from Hammad ibn ‘Uthaman who has said the following
“Abu ‘Abd Allah (a.s.), was asked about performing Salah (prayer) in ships. He (the Imam) said, ‘One must face al-Qiblah (al-Ka‘bah) and when it makes a turn, if one is able to face al- Qiblah (al-Ka‘bah) one must do so, otherwise, it is whichever direction it faces.’ He (the Imam) said, ‘If one can perform in a standing position, it must be done so, otherwise, one can sit down to perform his Salah (prayer).”’
2ـ عَلِيٌّ عَنْ أَبِيهِ وَمُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ جَمِيعاً عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حَمَّادِ بْنِ عُثْمَانَ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) أَنَّهُ سُئِلَ عَنِ الصَّلاَةِ فِي السَّفِينَةِ فَقَالَ
يَسْتَقْبِلُ الْقِبْلَةَ فَإِذَا دَارَتْ وَاسْتَطَاعَ أَنْ يَتَوَجَّهَ إِلَى الْقِبْلَةِ فَلْيَفْعَلْ وَإِلاَّ فَلْيُصَلِّ حَيْثُ تَوَجَّهَتْ بِهِ قَالَ فَإِنْ أَمْكَنَهُ الْقِيَامُ فَلْيُصَلِّ قَائِماً وَإِلاَّ فَلْيَقْعُدْ ثُمَّ لْيُصَلِّ.
