Israel has been waiting for Elijah:
Behold, I will send you Elijah the prophet before the coming of the great and terrible day of the LORD. Malachi 3 - 23
Elijah/Ilyas is mentioned in Saaffat:123-130.
And indeed, Elias was from among the messengers, (123) When he said to his people, "Will you not fear Allah? (124) Do you call upon Ba'l and leave the best of creators - (125) Allah, your Lord and the Lord of your first forefathers?" (126) And they denied him, so indeed, they will be brought [for punishment], (127) Except the chosen servants of Allah. (128) And We left for him [favorable mention] among later generations: (129) "Peace upon Elias." (130)
This verse is strange because the last verse is:
سَلَامٌ عَلَىٰ إِلْ يَاسِينَ
salamun ala il yaseen
Peace be upon Ilyas.
It says beforehand in chapter 36 Yasin.
Ya, Seen. (1) By the wise Qur'an. (2) Indeed you, [O Muhammad], are from among the messengers, (3) On a straight path.
Wikipedia says that Muhammad claimed that this refers to him, and is one of his names:
Yā Sīn is also one of the names of the Prophet Muhammad, as reported in a saying of Ali, "I heard the Messenger of God say, 'Verily God has named me by seven names in the Quran: Muhammad [3:144; 33:40; 47:2; 48:29], Ahmad [61:6], Tā Hā [20:1], Yā Sīn [36:1], thou enwrapped [al-Muzammil; 73:1], thou who art covered [al-Mudaththir; 74:1], and servant of God [ʿAbd Allāh; 72:19].'"
Is Muhammad the Elijah that the scriptures speak of?
