Under this alarming situation, Sayyiduna Musa tll!J1 was relaxed and was consoling the Israelites. When they approached the river, Allah jz_;’;i commanded Sayyiduna Musa tll!J1 to strike the river with his staff. Therefore, the moment he tll!J1 «;Ji struck the river with his blessed staff, twelve clear roads developed across the river. The Israelites walked over these twelve paths and crossed the river safely.
When pharaoh reached the river and saw the twelve roads, he went onto the roads along with his army. However, when he and his army reached the middle of the river, suddenly the huge waves rose and engulfed the roads. Consequently, pharaoh drowned into the river, along with his army. The Holy Quran mentions the incident in these words:
And then the two groups came in front of each other; those with Musa said, ‘They have overtaken us.’ Said Musa, ‘Not so! Indeed my Lord is with me, He will now show me the way.’ So We sent revelation to Musa; that, ‘Strike the river with your staff.’ Thereupon the river parted, so each part became like a huge mountain. And We brought the others (Fir’awn and his people) close to that place. And We saved Musa and all those with him. Then drowned the others. Indeed, in this is surely a sign and most of them were not Muslims.
