Al-Mu'jam al-Awsat 6136 — the Prophet ﷺ said: The means of safety

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: "The means of safety from drowning for my Ummah, when they board ships or travel on the sea, is that they say: 'Bismillahil-Malik, wa ma qadarullaha haqqa qadrihi wal-ardu jami'an qabdatuhu yawmal-qiyamati was-samawatu matwiyyatun bi-yaminihi, subhanahu wa ta'ala 'amma yushrikun, bismillahi majreha wa mursaha inna rabbi la-ghafurun rahim' (In the name of Allah, the King (I begin the journey). They did not appraise Allah with His true worth, while on the Day of Resurrection the whole earth will be within His grip and the heavens will be folded in His right hand; glorified and exalted is He above what they associate with Him. In the name of Allah is its (the ship's) course and its anchorage; indeed my Lord is Most Forgiving, Most Merciful)."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from al-Dahhak bin Muzahim (may Allah have mercy on him) except Nahshal bin Sa'id."
