Walamma waqaAAa AAalayhimu arrijzuqaloo ya moosa odAAu lana rabbaka bimaAAahida AAindaka la-in kashafta AAanna arrijzalanu/minanna laka walanursilanna maAAaka banee isra-eel

And when the punishment descended upon them, they said, "O Moses, invoke for us your Lord by what He has promised you. If you [can] remove the punishment from us, we will surely believe you, and we will send with you the Children of Israel."

Whenever a scourge befell them, they said, “O Mūsā, pray for us to your Lord by the covenant He has made with you. If you remove the scourge from us, we will truly believe in you, and will send the children of Isrā’īl with you.”
