3. Ali has narrated from ‘Abd Allah ibn al-Mughirah from certain persons of his people who has said the following: “I once asked abu ‘Abd Allah (a.s.), about a man who is in a ship and does not know the direction of al-Qiblah (al-Ka‘bah). He (the Imam) said, ‘He must make an effort to find the direction al-Qiblah (al-Ka‘bah) and if he cannot find it, performs Salah (prayer) facing toward where its head is.’”

4. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Yazid ibn Ishaq from Harun ibn Hamzah al-Ghanawiy who has said the following: “I once asked abu ‘Abd Allah (a.s.), about the case of Salah (prayer) in the ship. He (the Imam) said, ‘If it is heavily loaded and when you stand up it does not shake, perform Salah (prayer) in a standing position, but if it is light that can turn upside down, then perform Salah (prayer) in a sitting position.’”

5. Ali ibn Muhammad has narrated from Sahl ibn Ziyad from abu Hashim al-Ja‘fariy who has said the following: “One abu al-Hassan (a.s.), and I were in a ship on the Tigris. It became time for Salah (prayer) and I said, ‘I pray to Allah to keep my soul in service for your cause, can we perform Salah (prayer) in congregation? He (the Imam) said, ‘No, we perform Salah (prayer) in the valley in congregation.’”

1. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Faddal from ibn Bukayr from Zurarah who has said the following: “I went to visit abu Ja‘far (a.s.). I was a young person. The Imam described for me optional Salawat (prayers) and fasting and he noticed from my face that I considered it heavy. He then said to me, This is not like obligatory Salawat (prayers), so that on neglecting, one is destroyed. It is optional and if you cannot do on time, you can do compensatory prayer for it. They disliked that their deeds are taken up one day complete and one day incomplete. Allah, the Most Majestic, the Most Glorious, says, “Those who perform their Salah (prayer) all the time” (71:23). They (true Muslims) disliked continuing Salah (prayer) until sun declines on midday to the west; the doors of heaven open on such time.’”” (The meaning of ’all the time’, is not performing Salah (prayer) without any intervals).
