Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates from Sayyiduna Ja'far (may Allah be pleased with him): The Noble Prophet (peace and blessings be upon him) instructed him: "He should perform the prayer standing, except in the case where he fears drowning." Imam Daraqutni states: What is meant is that he should perform the prayer standing in the boat.

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.

Abdullah bin Umar (may Allah be pleased with them both) narrates: The Prophet (peace and blessings be upon him) was asked about performing prayer on a boat, so he said: "It should be performed standing, except if you fear drowning (then the ruling is different)."

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates the statement of the Noble Prophet (peace and blessings be upon him): "Whoever combines two prayers without a valid excuse will have committed a major sin." The Shaykh says: Hanash Abu Ali Rahbi is the narrator, and he is abandoned (matruk).
