The Journey Across the Red Sea

The clear and detailed Quran doesn't actually name the sea.

Moses strikes the sea:

S 20:77 And we inspired Musa: Travel by night with my slaves and strike a way for them in the sea, dry, not fearing a path nor fearing.

S 26:63 Then we inspired Musa: Strike the sea with your staff. Then it split apart and each part was like the great Tawd.

Tawd is a garbled form of the Syriac tur 'mountain'. The article is prefixed, so what mountain is in the author's mind? Sinai? Was the author uncertain as to how many parts the sea was split into?

Crossing and passing beyond:

S 7:138 And we crossed the sea with the Banu Isra’il. Then they came upon a people devoting themselves to idols of theirs. They said: Musa, make us a god like what gods they have. He said: You are ignorant people.

S 10:90 And we passed beyond the sea with the Banu Isra’il and Fir’awn and his troops followed them in rebellion and enmity until when the drowning came suddenly upon them, he said: I have believed that there is no god but the one whom the Banu Isra’il has believed in and I am of the Muslims.

'We' crossed and passed beyond the sea. Did Allah accompany the Israelites? Did they sail across it? Did the author have a hazy recollection of the pillar of cloud and of fire as recorded in Exodus 13?

21And the LORD went before them in a pillar of cloud to guide their way by day, and in a pillar of fire to give them light by night, so that they could travel by day or night. 22Neither the pillar of cloud by day nor the pillar of fire by night left its place before the people.

Allah parts the sea:

S 2:50 And when we parted the sea for you we saved you and drowned Fir’awn’s family while you look.

A hadith says:

Narrated Ikrimah:

The Holy Prophet (ﷺ) said to Ibn Suriya': I remind you by Allah Who saved you from the people of Pharaoh, made you cover the sea, gave you the shade of clouds, sent down to you manna and quails, sent down you Torah to Moses, do you find stoning (for adultery) in your Book? He said: You have reminded me by the Great. It is not possible for me to belie you. He then transmitted the rest of the tradition.

The word translated 'made you cover' is from the verb qata'a' 'to cut'. Did the Israelites part the sea?
