Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: When the Prophet Muhammad (peace and blessings be upon him) sent Sayyiduna Ja’far bin Abi Talib (may Allah be pleased with him) to Abyssinia, he asked:“O Messenger of Allah! How should we perform prayer on a boat?”The Prophet Muhammad (peace and blessings be upon him) said:“Perform prayer standing in it, but if you fear drowning (then perform prayer sitting).”One of the narrators of this narration, Husayn bin ‘Alwan, is abandoned.
