101 Dua’a: For safety from drowning 
Another tradition from Imam Jafar Sadiq (a.s) asked one to recite the following prayer if one is afraid of drowning: 
Transliteration: INNA VALI-YEYAL-LAHOOL-LAZI NAZZALAL-KITABA WA HOVAL YATAVAL-LAS-SALEHEEN
WA MA QADAROOL-LAHA HAQQA QADERHI VAL-ARZO JAMI'AN QABZATOHOO YAVMAL-QIYAMATE VAS-SAMAVATO MATVI-YATOOM BE-YAMINEHI SOBHANAHOO WA TA'ALA AMMA YOOSHREKOON 
Verily my protector is God who sent down the Book (Qur’an) and he guardeth the virtuous once. (7: 196) 
They have esteemed not God, as is His due: while the whole earth shall be in His grip on the Day of Judgment and heavens rolled up (shall be) in His right hand, Hallowed is He, and Exalted is He, high above what they associate (with Him). (39: 67)
